bit 7
Unimplemented: Read as ‘0’
ENDRHI: Enable Drive High bit
1 = CANTX pin will drive V
0 = CANTX pin will be 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
Note 1: Always set this bit when using differential bus to avoid signal crosstalk in CANTX
