• BCR0 (Address = H'006)
Bits 8 to 15: Reserved. The written value should always be ‘0’ and the returned value is ‘0’.
Bits 7 to 0—Baud Rate Pre-scale (BRP[7:0] = BCR0 [7:0]): These bits are used to define the
peripheral bus clock periods contained in a Time Quantum.

Segment for establishing synchronisation of nodes on the CAN bus. (Normal bit
edge transitions occur in this segment.)
Segment for compensating for physical delay between networks.
Buffer segment for correcting phase drift (positive). (This segment is extended
when synchronisation (resynchronisation) is established.)
Buffer segment for correcting phase drift (negative). (This segment is shortened
when synchronisation (resynchronisation) is established)
