●
ST7 Interface: buffering of the ST7 internal bus and address decoding of the CAN
registers.
TX/RX Buffers: three 10-byte buffers for transmission and reception of maximum length
messages.
ID Filters: two 12-bit compare and don’t care masks for message acceptance filtering.
PSR: page selection register (see memory map).
BRPR: clock divider for different data rates.
BTR: bit timing register.
ICR: interrupt control register.
ISR: interrupt status register.
CSR: general purpose control/status register.
TECR: transmit error counter register.
RECR: receive error counter register.
BTL: bit timing logic providing programmable bit sampling and bit clock generation for
synchronization of the controller.
BCDL: bit coding logic generating a NRZ-coded datastream with stuff bits.
SHREG: 8-bit shift register for serialization of data to be transmitted and parallelisation
of received data.
CRC: 15-bit CRC calculator and checker.
EML: error detection and management logic.
CAN Core: CAN 2.0B passive protocol controller.
