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.

SYNC_SEG:
Segment for establishing synchronisation of nodes on the CAN bus. (Normal bit
edge transitions occur in this segment.)
PRSEG:
Segment for compensating for physical delay between networks.
PHSEG1:
Buffer segment for correcting phase drift (positive). (This segment is extended
when synchronisation (resynchronisation) is established.)
PHSEG2:
Buffer segment for correcting phase drift (negative). (This segment is shortened
when synchronisation (resynchronisation) is established)
TSEG1:
TSG1 + 1
