In a latchup condition, supply current can increase dramatically and may destroy semiconductor elements. In using semiconductor devices, always take sufficient care to avoid exceeding maximum ratings. Also care must be taken when power to analog systems is switched on or off, to ensure that the analog power supply (AVCC, AVRH) , analog input and dedicated power supply for the high current output buffer pins (DVCC) do not exceed the digital power supply (VCC) . Once the digital power supply (VCC) is switched on, the analog power (AVCC,AVRH) and dedicated power supply for the high current output buffer pins (DVCC) may be turned on in any sequence. * Stable supply voltage Even within the warranted operating range of VCC supply voltage, sudden fluctuations in supply voltage can cause abnormal operation. The recommended stability for ripple fluctuations (P-P values) at commercial frequencies (50 Hz to 60 Hz) should be within 10% of the standard VCC value, and voltage fluctuations that occur during switching of power supplies etc. should be limited to transient fluctuation rates of 0.1 V/ms or less. * Power-on procedures In order to prevent abnormal operation of the internal built-in step-down circuits, voltage rise time during poweron should be attained within 50 s (0.2 V to 2.7 V) . * Treatment of unused pins If unused input pins are left open, they may cause abnormal operation or latchup which may lead to permanent damage to the semiconductor. Any such pins should be pulled up or pulled down through resistance of at least 2 k. Any unused input/output pins should be left open in output status, or if found set to input status, they should be treated in the same way as input pins. Any unused output pins should be left open. * Treatment of A/D converter power supply pins Even if the A/D converter is not used, pins should be connected so that AVCC = VCC, and AVSS = AVRH = VSS. * Use of external clock signals Even when an external clock is used, a stabilization period is required following a power-on reset or release from sub clock mode or stop mode. Also, when an external clock is used it should drive only the X0 pin and the X1 pin should be left open, as shown in the following figure. X0 OPEN X1 MB90420G/425G Series Sample external clock connection DS07-13711-5E 13 MB90420G/425G Series * Power supply pins Devices are designed to prevent problems such as latchup when multiple VCC and VSS supply pins are used, by providing internal connections between pins having the same potential. However, in order to reduce unwanted radiation, and to prevent abnormal operation of strobe signals due to rise in ground level, and to maintain total output current ratings, all such pins should always be connected externally to power supplies and ground. As shown in figure below, all VCC power supply pins must have the same potential. All VSS power supply pins should be handled in the same way. If there are multiple VCC or VSS systems, the device will not operate properly even within the warranted operating range. VCC VSS VCC VSS VSS VCC VCC VSS VSS VCC Power supply input pins (VCC/VSS) In addition, care must be given to connecting the VCC and VSS pins of this device to a current source with as little impedance as possible. It is recommended that a bypass capacitor of 1.0 F be connected between VCC and VSS as close to the pins as possible. * Proper sequence of A/D converter power supply analog input A/D converter power (AVCC, AVRH) and analog input (AN0-AN7) must be applied after the digital power supply (VCC) is switched on. When power is shut off, the A/D converter power supply and analog input must be cut off before the digital power supply is switched on (VCC) . In both power-on and shut-off, care should be taken that AVRH does not exceed AVCC. Even when pins which double as analog input pins are used as input ports, be sure that the input voltage does not exceed AVCC. (There is no problem if analog power supplies and digital power supplies are turned off and on at the same time.) * Handling the power supply for high-current output buffer pins (DVCC, DVSS) Always apply power to high-current output buffer pins (DVCC, DVSS) after the digital power supply (VCC) is turned on. Also when switching power off, always shut off the power supply to the high-current output buffer pins (DVCC, DVSS) before switching off the digital power supply (VCC) . (There will be no problem if high-current output buffer pins and digital power supplies are turned off and on at the same time.) Even when high-current output buffer pins are used as general purpose ports, the power for high current output buffer pins (DVCC, DVSS) should be applied to these pins. * Pull-up/pull-down resistance The MB90420G/425G series does not support internal pull-up/pull-down resistance. If necessary, use external components. 14 DS07-13711-5E MB90420G/425G Series * Precautions for when not using a sub clock signal. If the X0A and X1A pins are not connected to an oscillator, apply pull-down treatment to the X0A pin and leave the X1A pin open. * Notes on during operation of PLL clock mode If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even when there is no external oscillator or external clock input is stopped. Performance of this operation, however, cannot be guaranteed.

The lower 16-bit address for the FF bank will be assigned to the same address, so that tables in ROM can be referenced without declaring a "far" indication with the pointer. For example when accessing the address 00C000H, the actual access is to address FFC000H in ROM. Here the FF bank ROM area exceeds 48 KB, so that it is not possible to see the entire area in the 00 bank image. Therefore because the ROM data from FF4000H to FFFFFFH will appear in the image from 004000H to 00FFFFH, it is recommended that the ROM data table be stored in the area from FF4000H to FFFFFFH.

Watchdog Timer/Time Base Timer/Watch Timer The watchdog timer, timer base timer, and watch timer have the following circuit configuration. * Watchdog timer : Watchdog counter, control register, watchdog reset circuit * Time base timer : 18-bit timer, interval interrupt control circuit * Watch timer : 15-bit timer, interval interrupt control circuit (1) Watchdog timer function The watchdog timer is composed of a 2-bit watchdog counter that uses the carry signal from the 18-bit time base timer or 15-bit watch timer as a clock source, plus a control register and watchdog reset control circuit. After startup, this function will reset the CPU if not cleared within a given time. (2) Time base timer function The time base timer is an 18-bit free-run counter (time base counter) synchronized with the internal count clock (base oscillator divided by 2) , with an interval timer function providing a selection of four interval times. Other functions include a timer output for an oscillator stabilization wait time and clock feed to the watchdog timer or other operating clocks. Note that the time base timer uses the main clock regardless of the setting of the MCS bit or SCS bit in the CKSCR register. (3) Watch timer function The watch timer provides functions including a clock source for the watchdog timer, a sub clock base oscillator stabilization wait timer, and an interval timer to generate an interrupt at fixed intervals. Note that the watch timer uses the sub clock regardless of the setting of the MCS bit or SCS bit in the CKSCR register. 36 DS07-13711-5E MB90420G/425G Series * Block Diagram Main base oscillator divided by 2 TBTC TBC1 Selector TBC0 TBR TBIE AND Q 211 213 216 218 TBTRES Clock input Time base timer 211 213 216 218 S R TBOF Time base interrupt WDTC WT1 Selector 2-bit counter OF CLR WT0 Watchdog reset generator circuit CLR WTE To WDGRST internal reset generator circuit F2MC-16LX bus WTC WDCS SCE AND Q SCM Power-on reset, sub-clock stop S R WTC2 to WTC0 Selector WTR WTIE WTOF AND Q S R 28 29 210 211 212 213 214 216 WTRES 210 213 214 216 Watch timer Clock input Sub base oscillator divided by 4 Watch interrupt WDTC PONR From power-on generator WRST ERST RST pin SRST From RST bit in LPMCR register DS07-13711-5E 37 MB90420G/425G Series 3. Input Capture This circuit is composed of a 16-bit free-run timer and four 16-bit input capture circuits. (1) Input capture ( x 4) The input capture circuits consist of four independent external input pins and corresponding capture registers and control registers. When the specified edge of the external signal input (at the input pin) is detected, the value of the 16-bit free-run timer is saved in the capture register, and at the same time an interrupt can also be generated. * The valid edge (rising edge, falling edge, both edges) of the external signal can be selected. * The four input capture circuits can operate independently. * The interrupt can be generated from the valid edge of the external input signal. (2) 16-bit free-run timer ( x 1) The 16-bit free-run timer is composed of a 16-bit up-counter, control register, 16-bit compare register, and prescaler. The output values from this counter are used as the base time for the input capture circuits. * The counter clock operation can be selected from 8 options. The eight internal clock settings are , /2, /4, /8, /16, /32, /64, /128 where represents the machine clock cycle. * Interrupts can be generated from overflow events, or from compare match events with the compare register. (Compare match operation requires a mode setting.) * The counter value can be initialized to "0000H" by a reset, soft clear, or a compare match with the compare register.

The user may select either function. This timer defines a transition from 0000H to FFFFH as an underflow event. Thus an underflow occurs when counting from the value [Reload register setting + 1]. A selection of two counter operating modes are available. In reload mode, the counter is reset to the count value and continues counting after an underflow, and in one-shot mode the count stops after an underflow. The counter can generate an interrupt when an underflow occurs, and is compatible with the expanded intelligent I/O services (EI2OS) .

(3) Event count mode (External clock mode) In this mode a down count event occurs when a selected valid edge (rising, falling, both edges) is input at the TIN0/1 pin. This function can also be used as an interval timer when an external clock with a fixed period is used. (4) Counter operation * Reload mode In down count operation, when an underflow event (transition from "0000H" to "FFFFH") occurs, the set count value is reloaded and count operation continues. The function can be used as an interval timer by generating an interrupt request at each underflow event. Also, a toggle waveform that inverts at each underflow can be output from the TOT0/1 pin.

DS07-13711-5E 39 MB90420G/425G Series (5) One-shot mode In down count operation, the count stops when an underflow event (transition from "0000H" to "FFFFH") occurs. This function can generate an interrupt at each underflow. While the counter is operating, a rectangular wave form indicating that the count is in progress can be output form the TOT0 and TOT1 pins.

Real Time Watch Timer The real time watch timer is composed of a real time watch timer control register, sub second data register, second/minute/hour data registers, 1/2 clock divider, 21-bit prescaler and second/minute/hour counters. Because the MCU oscillation frequency operates on a given real time watch timer operation, a 4 MHz frequency is assumed.

PPG Timer The PPG timer consists of a prescaler, one 16-bit down-counter, 16-bit data register with buffer for period setting, and 16-bit compare register with buffer for duty setting, plus pin control circuits. The timer can output pulses synchronized with an externally input soft trigger. The period and duty of the output pulse can be adjusted by rewriting the values in the two 16-bit registers. (1) PWM function Programmable to output a pulse, synchronized with a trigger. Can also be used as a D/A converter with an external circuit. (2) One-shot function Detects the edge of a trigger input, and outputs a single pulse.

Delayed Interrupt Generator Module The delayed interrupt generator module is a module that generates interrupts for task switching. This module makes it possible to use software to generate/cancel interrupt requests to the F2MC-16LX CPU. * Block diagram F2MC-16LX bus Delayed interrupt source generate/delete decoder Source latch 44 DS07-13711-5E MB90420G/425G Series 8. DTP/External Interrupt Circuit The DTP (Data transfer peripheral) /external interrupt circuit is located between an externally connected peripheral device and the F2MC-16LX CPU and sends interrupt requests or data transfer requests generated from the peripheral device to the CPU, thereby generating external interrupt requests or starting the expanded intelligent I/O services (EI2OS) . (1) DTP/external interrupt function The DTP/external interrupt function uses a signal input from the DTP/external interrupt pin as a startup source. And it is accepted by the CPU by the same procedure as a normal hardware interrupt, and can generate an external interrupt or start the expanded intelligent I/O service (EI2OS) . When the interrupt is accepted by the CPU, if the corresponding expanded intelligent I/O service (EI2OS) is prohibited the interrupt operates as an external interrupt function and branches to an interrupt routine. If the EI2OS is permitted the interrupt functions as a DTP function, using EI2OS for automatic data transfer, then branching to an interrupt routine after the completion of the specified number of data transfers.

The input signal is selected from 8-channel analog input pins, and the conversion start can be selected from three types : by software, 16-bit reload timer 1 or a trigger input from an external signal pin. (1) 8/10-bit A/D converter functions The A/D converter takes analog voltage signals (input voltage) input at analog input pins, and converts these to digital values, providing the following features. * Minimum conversion time is 6.13 s (at machine clock frequency of 16 MHz, including sampling time) . * Minimum sampling time is 3.75 s (at machine clock 16 MHz) * The conversion method is an RC sequential conversion in comparison with a sample hold circuit. * Either 10-bit or 8-bit resolution can be selected. * The analog input pin can select from 8 channels by a program setting. * At completion of A/D conversion, an interrupt request can be generated, or EI2OS can be started. * Because the conversion data protection function operates in an interrupt enabled state, no data is lost even in continuous conversion. * The conversion start source may be selected from : software, 16-bit reload timer 1 (rising edge) , or external trigger input (falling edge) .

Low voltage/Program Looping Detection Reset Circuit The Low voltage detection reset circuit is a function that monitors power supply voltage in order to detect when a voltage drops below a given voltage level. When a low voltage condition is detected, an internal reset signal is generated. The Program Looping detection reset circuit is a count clock with a 20-bit counter that generates an internal reset signal if not cleared within a given time after startup. (1) Low voltage detection reset circuit Detection voltage 4.0 V 0.3 V When a low voltage condition is detected, the low voltage detection flag (LVRC : LVRF) is set to "1" and an internal reset signal is output. Because the low voltage detection circuit continues to operate even in stop mode, detection of a low voltage condition generates an internal reset and releases stop mode. During an internal RAM write cycle, an internal reset is generated after the completion of writing. During the output of this internal reset, the reset output from the low voltage detection circuit is suppressed. (2) Program Looping detection reset circuit The Program Looping detection reset circuit is a counter that prevents program looping. The counter starts automatically after a power-on reset, and must be continually cleared within a given time. If the given time interval elapses and the counter has not been cleared, a cause such as infinite program looping is assumed and an internal reset signal is generated. The internal reset generated form the Program Looping detection circuit has a width of 5 machine cycles. Interval duration 220/FC (Approx. 262 ms *) * : This value assumes an oscillation clock waveform of 4 MHz. During recovery from standby mode the detection period is the maximum interval plus 20 s. This circuit does not operate in modes where CPU operation is stopped. The Program Looping detection reset circuit counter is cleared under any of the following conditions. 1. Writing "0" to the LVRC register CL bit 2. Internal reset 3. Main oscillation clock stop 4. Transition to sleep mode 5.

Stepping Motor Controller The stepping motor controller is composed of two PWM pulse generators, four motor drivers and selector logic circuits. The four motor drivers have a high output drive capacity and can be directly connected to the four ends of two motor coils. They are designed to operate together with the PWM pulse generators and selector logic circuits to control motor rotation. A synchronization mechanism assures synchronization of the two PWM pulse generators. * Block diagram Machine clock OE1 Prescaler CK PWM1Pn PWM1 pulse generator EN P1 Output enable Selector PWM PWM1Mn P0 PWM1 compare register PWM1 selector register OE2 Output enable CK SC PWM2Pn PWM2 pulse generator CE EN Selector PWM PWM2Mn Load PWM2 compare register DS07-13711-5E BS PWM2 select register n:0~3 57 MB90420G/425G Series 15.

Address Match Detect Function If the address setting is the same as the address detection register, an INT9 instruction is executed. The integrated address match detection function can be implemented by processing the INT9 interrupt service routine. Two address registers are used, each with its own compare enable bit. When there is a match between the address register and program counter, and the compare enable bit is set to "1" , the INT9 instruction is forcibly executed by the CPU.
