This capability is available in HDLC CS=1 mode only. In order to use this new functionality bit #9 of the channel specification, which is called NSF (=no short frame indication), has to be set to a logical '1'. 31 30 29 28 27 26 25 24 Interrupt Mask 23 22 21 20 19 18 17 16 NITBS RI TI TO TA TH RO RA 0 0 0 0 0 0 0 FRDA FTDA 0 0 15 14 0 13 0 12 0 11 0 10 TFLAG 0 0 0 9 8 7 6 TFLAG/ NSF TFLAG/ CS INV CRC 0 0 5 4 TRV 3 FA 2 1 Mode 0 IFTF FRDA FTDA 0 0 0 0 0 0 0 0 ITBS When this bit is set to '1' with CS=0 aborted frames (> 2 byte ) are written into the shared memory, last 2 bytes are invalid, ERR / CRC interrupt is generated, status RA bit is set. In all other modes ( HDLC protocol ) this bit has to be set to logical '0'! The new mode has all features of the HDLC mode with the following changes: * * * * In case of 1 Byte (or greater) frame received, the data is copied to the RAM The short frame interrupt is not generated! The short frame status bit is not set the same way as described in HDLC case The FI interrupt is generated the same way as described in HDLC case Note: CRC is still calculated and checked and e.g. a frame of 1 or 2 Byte length (in CRC16 Mode) will always cause an FI+ERR interrupt. Semiconductor Group 4 12.97 PEB 20320 PEF 20320 Examples: a) 0x7E, data1, 0x7E... * data1 in RAM * status SF-Bit set * FI indication interrupt generated * No SF interrupt * ERR interrupt due to wrong CRC b) 0x7E, data=0xFC(or 0xFD, or 0x7F), 0x7E * no data in RAM * SF, ERR-interrupt 1.3.2 Reset The RESET behaviour was changed between MUNICH32 V3.3 and MUNICH32 V3.4: After power up a logical '1' at the reset pin of the MUNICH32 V3.4 sets the device into a reset state where the complete microprocessor bus interface is tristated and the internal reset sequence is started. The trailing edge of the reset starts the last part of the internal reset sequence and takes about 12 SCLK clock cycles. It is not allowed to give an AR during these first 12 SCLK cycles after the trailing edge of RESET. 1.3.3 New version number The version number is identified in the interrupt information bits VN(3:1): these bits are '110' for version 3.4. The version number in the boundary scan ID code is set to '0110' for version 3.4. 1.4 Electrical Characteristics The MUNICH32 V3.4 is available for the extended range of temperature: Ambient temperature ratings Parameter Symbol Limit Values Unit Ambient temperature under bias: PEB PEF TA TA 0 to 70 -40 to 85 C C All other electrical characteristics are as specified in MUNICH32 User's Manual 01.96.
