23.2.5 CAN MODULE I/O CONTROL
REGISTER
This register controls the operation of the CAN moduleâs
I/O pins in relation to the rest of the microcontroller.

Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
â1â = Bit is set
U = Unimplemented bit, read as â0â
â0â = Bit is cleared
x = Bit is unknown
bit 7-6
bit 5
bit 4
bit 3-0
Unimplemented: Read as â0â
ENDRHI: Enable Drive High bit(1)
1 = CANTX pin will drive VDD when recessive
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 â0â
Note 1: Always set this bit when using differential bus to avoid signal crosstalk in CANTX from other nearby pins.
