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
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
Legend:
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
Note: This register is accessible in Configuration mode only.
