Unimplemented: Read as ‘0’
ENDRHI: Enable Drive High bit
1 = CANTX pin will drive V
0 = CANTX pin will tri-state when recessive
CANCAP: CAN Message Receive Capture Enable bit
1 = Enable CAN capture, CAN message receive signal replaces input on RC2/CCP1
0 = Disable CAN capture, RC2/CCP1 input to CCP1 module
Unimplemented: Read as ’0’
Legend:
R = Readable bit
- n = Value at POR
Unimplemented: Read as ’0’
WAKFIL: Selects CAN bus Line Filter for Wake-up bit
1 = Use CAN bus line filter for wake-up
0 = CAN bus line filter is not used for wake-up
Unimplemented: Read as ’0’
SEG2PH2:SEG2PH0: Phase Segment 2 Time Select bits
111 = Phase Segment 2 Time = 8 x T
110 = Phase Segment 2 Time = 7 x T
101 = Phase Segment 2 Time = 6 x T
100 = Phase Segment 2 Time = 5 x T
011 = Phase Segment 2 Time = 4 x T
010 = Phase Segment 2 Time = 3 x T
001 = Phase Segment 2 Time = 2 x T
000 = Phase Segment 2 Time = 1 x T
Legend:
R = Readable bit
- n = Value at POR
Note 1: Ignored if SEG2PHTS bit (BRGCON2<7>) is clear.
