The 2G4RF_ION pin should be grounded externally. The external components and power supply connections for the antenna interface typical applications are shown in the RF Matching Networks section. silabs.com | Building a more connected world. Rev. 1.5 | 9 EFR32MG12 Gecko Multi-Protocol Wireless SoC Family Data Sheet System Overview 3.2.2 Fractional-N Frequency Synthesizer The EFR32MG12 contains a high performance, low phase noise, fully integrated fractional-N frequency synthesizer. The synthesizer is used in receive mode to generate the LO frequency used by the down-conversion mixer. It is also used in transmit mode to directly generate the modulated RF carrier. The fractional-N architecture provides excellent phase noise performance combined with frequency resolution better than 100 Hz, with low energy consumption. The synthesizer has fast frequency settling which allows very short receiver and transmitter wake up times to optimize system energy consumption. 3.2.3 Receiver Architecture The EFR32MG12 uses a low-IF receiver architecture, consisting of a Low-Noise Amplifier (LNA) followed by an I/Q down-conversion mixer, employing a crystal reference. The I/Q signals are further filtered and amplified before being sampled by the IF analog-to-digital converter (IFADC). The IF frequency is configurable from 150 kHz to 1371 kHz. The IF can further be configured for high-side or low-side injection, providing flexibility with respect to known interferers at the image frequency. The Automatic Gain Control (AGC) block adjusts the receiver gain to optimize performance and avoid saturation for excellent selectivity and blocking performance. The 2.4 GHz radio is calibrated at production to improve image rejection performance. The sub-GHz radio can be calibrated on-demand by the user for the desired frequency band. Demodulation is performed in the digital domain. The demodulator performs configurable decimation and channel filtering to allow receive bandwidths ranging from 0.1 to 2530 kHz. High carrier frequency and baud rate offsets are tolerated by active estimation and compensation. Advanced features supporting high quality communication under adverse conditions include forward error correction by block and convolutional coding as well as Direct Sequence Spread Spectrum (DSSS) for 2.4 GHz and sub-GHz bands. A Received Signal Strength Indicator (RSSI) is available for signal quality metrics, for level-based proximity detection, and for RF channel access by Collision Avoidance (CA) or Listen Before Talk (LBT) algorithms. An RSSI capture value is associated with each received frame and the dynamic RSSI measurement can be monitored throughout reception. The EFR32MG12 features integrated support for antenna diversity to mitigate the problem of frequency-selective fading due to multipath propagation and improve link budget. Support for antenna diversity is available for specific PHY configurations in 2.4 GHz and sub-GHz bands. Internal configurable hardware controls an external switch for automatic switching between antennae during RF receive detection operations. Note: Due to the shorter preamble of 802.15.4 and BLE packets, RX diversity is not supported. 3.2.4 Transmitter Architecture The EFR32MG12 uses a direct-conversion transmitter architecture. For constant envelope modulation formats, the modulator controls phase and frequency modulation in the frequency synthesizer. Transmit symbols or chips are optionally shaped by a digital shaping filter. The shaping filter is fully configurable, including the BT product, and can be used to implement Gaussian or Raised Cosine shaping. Carrier Sense Multiple Access - Collision Avoidance (CSMA-CA) or Listen Before Talk (LBT) algorithms can be automatically timed by the EFR32MG12. These algorithms are typically defined by regulatory standards to improve inter-operability in a given bandwidth between devices that otherwise lack synchronized RF channel access. 3.2.5 Wake on Radio The Wake on Radio feature allows flexible, autonomous RF sensing, qualification, and demodulation without required MCU activity, using a subsystem of the EFR32MG12 including the Radio Controller (RAC), Peripheral Reflex System (PRS), and Low Energy peripherals. silabs.com | Building a more connected world. Rev. 1.5 | 10 EFR32MG12 Gecko Multi-Protocol Wireless SoC Family Data Sheet System Overview 3.2.6 RFSENSE The RFSENSE peripheral generates a system wakeup interrupt upon detection of wideband RF energy at the antenna interface, providing true RF wakeup capabilities from low energy modes including EM2, EM3 and EM4. RFSENSE triggers on a relatively strong RF signal and is available in the lowest energy modes, allowing exceptionally low energy consumption. RFSENSE does not demodulate or otherwise qualify the received signal, but software may respond to the wakeup event by enabling normal RF reception. Various strategies for optimizing power consumption and system response time in presence of false alarms may be employed using available timer peripherals. 3.2.7 Flexible Frame Handling EFR32MG12 has an extensive and flexible frame handling support for easy implementation of even complex communication protocols. The Frame Controller (FRC) supports all low level and timing critical tasks together with the Radio Controller and Modulator/Demodulator: * Highly adjustable preamble length * Up to 2 simultaneous synchronization words, each up to 32 bits and providing separate interrupts * Frame disassembly and address matching (filtering) to accept or reject frames * Automatic ACK frame assembly and transmission * Fully flexible CRC generation and verification: * Multiple CRC values can be embedded in a single frame * 8, 16, 24 or 32-bit CRC value * Configurable CRC bit and byte ordering * Selectable bit-ordering (least significant or most significant bit first) * Optional data whitening * Optional Forward Error Correction (FEC), including convolutional encoding / decoding and block encoding / decoding * Half rate convolutional encoder and decoder with constraint lengths from 2 to 7 and optional puncturing * Optional symbol interleaving, typically used in combination with FEC * Symbol coding, such as Manchester or DSSS, or biphase space encoding using FEC hardware * UART encoding over air, with start and stop bit insertion / removal * Test mode support, such as modulated or unmodulated carrier output * Received frame timestamping 3.2.8 Packet and State Trace The EFR32MG12 Frame Controller has a packet and state trace unit that provides valuable information during the development phase. It features: * Non-intrusive trace of transmit data, receive data and state information * Data observability on a single-pin UART data output, or on a two-pin SPI data output * Configurable data output bitrate / baudrate * Multiplexed transmitted data, received data and state / meta information in a single serial data stream 3.2.9 Data Buffering The EFR32MG12 features an advanced Radio Buffer Controller (BUFC) capable of handling up to 4 buffers of adjustable size from 64 bytes to 4096 bytes. Each buffer can be used for RX, TX or both. The buffer data is located in RAM, enabling zero-copy operations. 3.2.10 Radio Controller (RAC) The Radio Controller controls the top level state of the radio subsystem in the EFR32MG12. It performs the following tasks: * Precisely-timed control of enabling and disabling of the receiver and transmitter circuitry * Run-time calibration of receiver, transmitter and frequency synthesizer * Detailed frame transmission timing, including optional LBT or CSMA-CA silabs.com | Building a more connected world. Rev. 1.5 | 11 EFR32MG12 Gecko Multi-Protocol Wireless SoC Family Data Sheet System Overview 3.2.11 Random Number Generator The Frame Controller (FRC) implements a random number generator that uses entropy gathered from noise in the RF receive chain. The data is suitable for use in cryptographic applications. Output from the random number generator can be used either directly or as a seed or entropy source for software-based random number generator algorithms such as Fortuna. silabs.com | Building a more connected world. Rev. 1.5 | 12 EFR32MG12 Gecko Multi-Protocol Wireless SoC Family Data Sheet System Overview 3.3 Power The EFR32MG12 has an Energy Management Unit (EMU) and efficient integrated regulators to generate internal supply voltages. Only a single external supply voltage is required, from which all internal voltages are created. An optional integrated DC-DC buck regulator can be utilized to further reduce the current consumption. The DC-DC regulator requires one external inductor and one external capacitor. The EFR32MG12 device family includes support for internal supply voltage scaling, as well as two different power domains groups for peripherals. These enhancements allow for further supply current reductions and lower overall power consumption. AVDD and VREGVDD need to be 1.8 V or higher for the MCU to operate across all conditions; however the rest of the system will operate down to 1.62 V, including the digital supply and I/O. This means that the device is fully compatible with 1.8 V components. Running from a sufficiently high supply, the device can use the DC-DC to regulate voltage not only for itself, but also for other PCB components, supplying up to a total of 200 mA. 3.3.1 Energy Management Unit (EMU) The Energy Management Unit manages transitions of energy modes in the device. Each energy mode defines which peripherals and features are available and the amount of current the device consumes. The EMU can also be used to turn off the power to unused RAM blocks, and it contains control registers for the DC-DC regulator and the Voltage Monitor (VMON). The VMON is used to monitor multiple supply voltages. It has multiple channels which can be programmed individually by the user to determine if a sensed supply has fallen below a chosen threshold. 3.3.2 DC-DC Converter The DC-DC buck converter covers a wide range of load currents and provides up to 90% efficiency in energy modes EM0, EM1, EM2 and EM3, and can supply up to 200 mA to the device and surrounding PCB components. Patented RF noise mitigation allows operation of the DC-DC converter without degrading sensitivity of radio components. Protection features include programmable current limiting, short-circuit protection, and dead-time protection. The DC-DC converter may also enter bypass mode when the input voltage is too low for efficient operation. In bypass mode, the DC-DC input supply is internally connected directly to its output through a low resistance switch. Bypass mode also supports in-rush current limiting to prevent input supply voltage droops due to excessive output current transients. 3.3.3 Power Domains The EFR32MG12 has two peripheral power domains for operation in EM2 and lower. If all of the peripherals in a peripheral power domain are configured as unused, the power domain for that group will be powered off in the low-power mode, reducing the overall current consumption of the device. Table 3.1. Peripheral Power Subdomains Peripheral Power Domain 1 Peripheral Power Domain 2 ACMP0 ACMP1 PCNT0 PCNT1 ADC0 PCNT2 LETIMER0 CSEN LESENSE DAC0 APORT LEUART0 - I2C0 - I2C1 - IDAC silabs.com | Building a more connected world. Rev. 1.5 | 13 EFR32MG12 Gecko Multi-Protocol Wireless SoC Family Data Sheet System Overview 3.4 General Purpose Input/Output (GPIO) EFR32MG12 has up to 65 General Purpose Input/Output pins. Each GPIO pin can be individually configured as either an output or input. More advanced configurations including open-drain, open-source, and glitch-filtering can be configured for each individual GPIO pin. The GPIO pins can be overridden by peripheral connections, like SPI communication. Each peripheral connection can be routed to several GPIO pins on the device. The input value of a GPIO pin can be routed through the Peripheral Reflex System to other peripherals. The GPIO subsystem supports asynchronous external pin interrupts. 3.5 Clocking 3.5.1 Clock Management Unit (CMU) The Clock Management Unit controls oscillators and clocks in the EFR32MG12. Individual enabling and disabling of clocks to all peripherals is performed by the CMU. The CMU also controls enabling and configuration of the oscillators. A high degree of flexibility allows software to optimize energy consumption in any specific application by minimizing power dissipation in unused peripherals and oscillators. 3.5.2 Internal and External Oscillators The EFR32MG12 supports two crystal oscillators and fully integrates four RC oscillators, listed below. * A high frequency crystal oscillator (HFXO) with integrated load capacitors, tunable in small steps, provides a precise timing reference for the MCU. Crystal frequencies in the range from 38 to 40 MHz are supported. An external clock source such as a TCXO can also be applied to the HFXO input for improved accuracy over temperature. * A 32.768 kHz crystal oscillator (LFXO) provides an accurate timing reference for low energy modes. * An integrated high frequency RC oscillator (HFRCO) is available for the MCU system, when crystal accuracy is not required. The HFRCO employs fast startup at minimal energy consumption combined with a wide frequency range. * An integrated auxilliary high frequency RC oscillator (AUXHFRCO) is available for timing the general-purpose ADC and the Serial Wire Viewer port with a wide frequency range. * An integrated low frequency 32.768 kHz RC oscillator (LFRCO) can be used as a timing reference in low energy modes, when crystal accuracy is not required. * An integrated ultra-low frequency 1 kHz RC oscillator (ULFRCO) is available to provide a timing reference at the lowest energy consumption in low energy modes. 3.6 Counters/Timers and PWM 3.6.1 Timer/Counter (TIMER) TIMER peripherals keep track of timing, count events, generate PWM outputs and trigger timed actions in other peripherals through the PRS system. The core of each TIMER is a 16-bit counter with up to 4 compare/capture channels. Each channel is configurable in one of three modes. In capture mode, the counter state is stored in a buffer at a selected input event. In compare mode, the channel output reflects the comparison of the counter to a programmed threshold value. In PWM mode, the TIMER supports generation of pulse-width modulation (PWM) outputs of arbitrary waveforms defined by the sequence of values written to the compare registers, with optional dead-time insertion available in timer unit TIMER_0 only. 3.6.2 Wide Timer/Counter (WTIMER) WTIMER peripherals function just as TIMER peripherals, but are 32 bits wide. They keep track of timing, count events, generate PWM outputs and trigger timed actions in other peripherals through the PRS system. The core of each WTIMER is a 32-bit counter with up to 4 compare/capture channels. Each channel is configurable in one of three modes. In capture mode, the counter state is stored in a buffer at a selected input event. In compare mode, the channel output reflects the comparison of the counter to a programmed threshold value. In PWM mode, the WTIMER supports generation of pulse-width modulation (PWM) outputs of arbitrary waveforms defined by the sequence of values written to the compare registers, with optional dead-time insertion available in timer unit WTIMER_0 only. 3.6.3 Real Time Counter and Calendar (RTCC) The Real Time Counter and Calendar (RTCC) is a 32-bit counter providing timekeeping in all energy modes.

The RTCC can be clocked by any of the on-board oscillators with the exception of the AUXHFRCO, and it is capable of providing system wake-up at user defined instances. When receiving frames, the RTCC value can be used for timestamping. The RTCC includes 128 bytes of general purpose data retention, allowing easy and convenient data storage in all energy modes down to EM4H. silabs.com | Building a more connected world.

This allows it to be used for timing and output generation when most of the device is powered down, allowing simple tasks to be performed while the power consumption of the system is kept at an absolute minimum. The LETIMER can be used to output a variety of waveforms with minimal software intervention. The LETIMER is connected to the Real Time Counter and Calendar (RTCC), and can be configured to start counting on compare matches from the RTCC. 3.6.5 Ultra Low Power Wake-up Timer (CRYOTIMER) The CRYOTIMER is a 32-bit counter that is capable of running in all energy modes. It can be clocked by either the 32.768 kHz crystal oscillator (LFXO), the 32.768 kHz RC oscillator (LFRCO), or the 1 kHz RC oscillator (ULFRCO). It can provide periodic Wakeup events and PRS signals which can be used to wake up peripherals from any energy mode. The CRYOTIMER provides a wide range of interrupt periods, facilitating flexible ultra-low energy operation. 3.6.6 Pulse Counter (PCNT) The Pulse Counter (PCNT) peripheral can be used for counting pulses on a single input or to decode quadrature encoded inputs. The clock for PCNT is selectable from either an external source on pin PCTNn_S0IN or from an internal timing reference, selectable from among any of the internal oscillators, except the AUXHFRCO. The peripheral may operate in energy mode EM0 Active, EM1 Sleep, EM2 Deep Sleep, and EM3 Stop. 3.6.7 Watchdog Timer (WDOG) The watchdog timer can act both as an independent watchdog or as a watchdog synchronous with the CPU clock. It has windowed monitoring capabilities, and can generate a reset or different interrupts depending on the failure mode of the system. The watchdog can also monitor autonomous systems driven by PRS. 3.7 Communications and Other Digital Peripherals 3.7.1 Universal Synchronous/Asynchronous Receiver/Transmitter (USART) The Universal Synchronous/Asynchronous Receiver/Transmitter is a flexible serial I/O interface. It supports full duplex asynchronous UART communication with hardware flow control as well as RS-485, SPI, MicroWire and 3-wire. It can also interface with devices supporting: * ISO7816 SmartCards * IrDA * I2S 3.7.2 Low Energy Universal Asynchronous Receiver/Transmitter (LEUART) The unique LEUARTTM provides two-way UART communication on a strict power budget. Only a 32.768 kHz clock is needed to allow UART communication up to 9600 baud. The LEUART includes all necessary hardware to make asynchronous serial communication possible with a minimum of software intervention and energy consumption. 3.7.3 Inter-Integrated Circuit Interface (I2C) The I2C interface enables communication between the MCU and a serial I2C bus. It is capable of acting as both a master and a slave and supports multi-master buses. Standard-mode, fast-mode and fast-mode plus speeds are supported, allowing transmission rates from 10 kbit/s up to 1 Mbit/s. Slave arbitration and timeouts are also available, allowing implementation of an SMBus-compliant system. The interface provided to software by the I2C peripheral allows precise timing control of the transmission process and highly automated transfers. Automatic recognition of slave addresses is provided in active and low energy modes. 3.7.4 Peripheral Reflex System (PRS) The Peripheral Reflex System provides a communication network between different peripherals without software involvement. Peripherals producing Reflex signals are called producers. The PRS routes Reflex signals from producers to consumer peripherals, which in turn perform actions in response. Edge triggers and other functionality such as simple logic operations (AND, OR, NOT) can be applied by the PRS to the signals. The PRS allows peripheral to act autonomously without waking the MCU core, saving power. silabs.com | Building a more connected world. Rev. 1.5 | 15 EFR32MG12 Gecko Multi-Protocol Wireless SoC Family Data Sheet System Overview 3.7.5 Low Energy Sensor Interface (LESENSE) The Low Energy Sensor Interface LESENSETM is a highly configurable sensor interface with support for up to 16 individually configurable sensors. By controlling the analog comparators, ADC, and DAC, LESENSE is capable of supporting a wide range of sensors and measurement schemes, and can for instance measure LC sensors, resistive sensors and capacitive sensors. LESENSE also includes a programmable finite state machine which enables simple processing of measurement results without CPU intervention. LESENSE is available in energy mode EM2, in addition to EM0 and EM1, making it ideal for sensor monitoring in applications with a strict energy budget. 3.8 Security Features 3.8.1 General Purpose Cyclic Redundancy Check (GPCRC) The GPCRC block implements a Cyclic Redundancy Check (CRC) function. It supports both 32-bit and 16-bit polynomials. The supported 32-bit polynomial is 0x04C11DB7 (IEEE 802.3), while the 16-bit polynomial can be programmed to any value, depending on the needs of the application. 3.8.2 Crypto Accelerator (CRYPTO) The Crypto Accelerator is a fast and energy-efficient autonomous hardware encryption and decryption accelerator. EFR32 devices support AES encryption and decryption with 128- or 256-bit keys, ECC over both GF(P) and GF(2m), SHA-1 and SHA-2 (SHA-224 and SHA-256). Supported block cipher modes of operation for AES include: ECB, CTR, CBC, PCBC, CFB, OFB, GCM, CBC-MAC, GMAC and CCM. Supported ECC NIST recommended curves include P-192, P-224, P-256, K-163, K-233, B-163 and B-233. The CRYPTO1 block is tightly linked to the Radio Buffer Controller (BUFC) enabling fast and efficient autonomous cipher operations on data buffer content. It allows fast processing of GCM (AES), ECC and SHA with little CPU intervention. CRYPTO also provides trigger signals for DMA read and write operations. 3.8.3 True Random Number Generator (TRNG) The TRNG is a non-deterministic random number generator based on a full hardware solution. The TRNG is validated with NIST800-22 and AIS-31 test suites as well as being suitable for FIPS 140-2 certification (for the purposes of cryptographic key generation). Note: TRNG operation is only supported at VSCALE2. TRNG cannot be used at VSCALE0. 3.8.4 Security Management Unit (SMU) The Security Management Unit (SMU) allows software to set up fine-grained security for peripheral access, which is not possible in the Memory Protection Unit (MPU). Peripherals may be secured by hardware on an individual basis, such that only priveleged accesses to the peripheral's register interface will be allowed. When an access fault occurs, the SMU reports the specific peripheral involved and can optionally generate an interrupt. 3.9 Analog 3.9.1 Analog Port (APORT) The Analog Port (APORT) is an analog interconnect matrix allowing access to many analog peripherals on a flexible selection of pins. Each APORT bus consists of analog switches connected to a common wire. Since many clients can operate differentially, buses are grouped by X/Y pairs. 3.9.2 Analog Comparator (ACMP) The Analog Comparator is used to compare the voltage of two analog inputs, with a digital output indicating which input voltage is higher. Inputs are selected from among internal references and external pins. The tradeoff between response time and current consumption is configurable by software. Two 6-bit reference dividers allow for a wide range of internally-programmable reference sources. The ACMP can also be used to monitor the supply voltage. An interrupt can be generated when the supply falls below or rises above the programmable threshold. silabs.com | Building a more connected world.

The VDAC is a fully differential, 500 ksps, 12-bit converter. The opamps are used in conjunction with the VDAC, to provide output buffering. One opamp is used per singleended channel, or two opamps are used to provide differential outputs. The VDAC may be used for a number of different applications such as sensor interfaces or sound output. The VDAC can generate high-resolution analog signals while the MCU is operating at low frequencies and with low total power consumption. Using DMA and a timer, the VDAC can be used to generate waveforms without any CPU intervention. The VDAC is available in all energy modes down to and including EM3. 3.9.7 Operational Amplifiers The opamps are low power amplifiers with a high degree of flexibility targeting a wide variety of standard opamp application areas, and are available down to EM3. With flexible built-in programming for gain and interconnection they can be configured to support multiple common opamp functions. All pins are also available externally for filter configurations. Each opamp has a rail to rail input and a rail to rail output. They can be used in conjunction with the VDAC peripheral or in stand-alone configurations. The opamps save energy, PCB space, and cost as compared with standalone opamps because they are integrated on-chip. 3.10 Reset Management Unit (RMU) The RMU is responsible for handling reset of the EFR32MG12.

When a GPIO pin is routed to the analog block through the APORT, the maximum voltage = IOVDD. 2. Valid for IOVDD in valid operating range or when IOVDD is undriven (high-Z). If IOVDD is connected to a low-impedance source below the valid operating range (e.g. IOVDD shorted to VSS), the pin voltage maximum is IOVDD + 0.3 V, to avoid exceeding the maximum IO current specifications. 3. To operate above the IOVDD supply rail, over-voltage tolerance must be enabled according to the GPIO_Px_OVTDIS register. Pins with over-voltage tolerance disabled have the same limits as Standard GPIO. silabs.com | Building a more connected world.

The maximum limit on TA may be lower due to device self-heating, which depends on the power dissipation of the specific application. TA (max) = TJ (max) - (THETAJA x PowerDissipation). Refer to the Absolute Maximum Ratings table and the Thermal Characteristics table for TJ and THETAJA. 2. VREGVDD must be tied to AVDD. Both VREGVDD and AVDD minimum voltages must be satisfied for the part to operate. 3. The minimum voltage required in bypass mode is calculated using RBYP from the DCDC specification table. Requirements for other loads can be calculated as VDVDD_min+ILOAD * RBYP_max. 4. When the CSEN peripheral is used with chopping enabled (CSEN_CTRL_CHOPEN = ENABLE), IOVDD must be equal to AVDD. 5. The system designer should consult the characteristic specs of the capacitor used on DECOUPLE to ensure its capacitance value stays within the specified bounds across temperature and DC bias. 6. VSCALE0 to VSCALE2 voltage change transitions occur at a rate of 10 mV / usec for approximately 20 usec. During this transition, peak currents will be dependent on the value of the DECOUPLE output capacitor, from 35 mA (with a 1 F capacitor) to 70 mA (with a 2.7 F capacitor). 4.1.3 Thermal Characteristics Table 4.3.

Specified configuration for Unit gain buffer configuration is: INCBW = 0, HCMDIS = 0, RESINSEL = DISABLE. VINPUT = 0.5 V, VOUTPUT = 0.5 V. 2. Specified configuration for 3X-Gain configuration is: INCBW = 1, HCMDIS = 1, RESINSEL = VSS, VINPUT = 0.5 V, VOUTPUT = 1.5 V. Nominal voltage gain is 3. 3. If the maximum CLOAD is exceeded, an isolation resistor is required for stability. See AN0038 for more information. 4. Current into the load resistor is excluded. When the OPAMP is connected with closed-loop gain > 1, there will be extra current to drive the resistor feedback network. The internal resistor feedback network has total resistance of 143.5 kOhm, which will cause another ~10 A current when the OPAMP drives 1.5 V between output and ground. 5. In unit gain connection, UGF is the gain-bandwidth product of the OPAMP. In 3x Gain connection, UGF is the gain-bandwidth product of the OPAMP and 1/3 attenuation of the feedback network. 6. Step between 0.2V and VOPA-0.2V, 10%-90% rising/falling range. 7. When INCBW is set to 1 the OPAMP bandwidth is increased. This is allowed only when the non-inverting close-loop gain is 3, or the OPAMP may not be stable. 8. From enable to output settled. In sample-and-off mode, RC network after OPAMP will contribute extra delay. Settling error < 1mV. 9. When HCMDIS=1 and input common mode transitions the region from VOPA-1.4V to VOPA-1V, input offset will change. PSRR and CMRR specifications do not apply to this transition region. 4.1.22 Pulse Counter (PCNT) Table 4.48.
