bit 7-6
bit 5
bit 4
bit 3-0
Unimplemented: Read as ‘0’
ENDRHI: Enable Drive High bit
1 = CANTX pin will drive VDD when recessive
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
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
