R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

SJW<1:0>: Synchronization Jump Width bits
11 = Length is 4 x TQ
10 = Length is 3 x TQ
01 = Length is 2 x TQ
00 = Length is 1 x TQ
BRP<5:0>: Baud Rate Prescaler bits
11 1111 = TQ = 2 x 64 x 1/FCAN⁽¹⁾

00 0010 = TQ = 2 x 3 x 1/FCAN⁽¹⁾
00 0001 = TQ = 2 x 2 x 1/FCAN⁽¹⁾
00 0000 = TQ = 2 x 1 x 1/FCAN⁽¹⁾
Note 1: FCAN is either FP or twice FP depending on the CANCKS bit (CiCTRL<11>) selection.
