CAN BAUD RATE REGISTERS
This section describes the CAN Baud Rate registers.
Note:
These
registers
are
writable
in
Configuration mode only.

bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-6
SJW1:SJW0: Synchronized Jump Width bits
11 = Synchronization jump width time = 4 x TQ
10 = Synchronization jump width time = 3 x TQ
01 = Synchronization jump width time = 2 x TQ
00 = Synchronization jump width time = 1 x TQ
bit 5-0
BRP5:BRP0: Baud Rate Prescaler bits
111111 = TQ = (2 x 64)/FOSC
111110 = TQ = (2 x 63)/FOSC
:
000001 = TQ = (2 x 2)/FOSC
000000 = TQ = (2 x 1)/FOSC
