Section 19 Controller Area Network (RCAN-TL1)
(3)
The bit configuration registers (BCR0 and BCR1) are 2 X 16-bit read/write register that are used
to set CAN bit timing parameters and the baud rate pre-scaler for the CAN Interface.
The Time quanta is defined as:
Where: BRP (Baud Rate Pre-scaler) is the value stored in BCR0 incremented by 1 and fclk is the
used peripheral bus frequency.
• BCR1 (Address = H'004)
Bits 15 to 12 — Time Segment 1 (TSG1[3:0] = BCR1[15:12]): These bits are used to set the
segment TSEG1 (= PRSEG + PHSEG1) to compensate for edges on the CAN Bus with a positive
phase error. A value from 4 to 16 time quanta can be set.
Bit 11: Reserved. The written value should always be ‘0’ and the returned value is ‘0’.
