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

bit 7-6

bit 5

bit 4

bit 3-0

Unimplemented: Read as ‘0’

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 ‘0’

Note 1: Always set this bit when using a differential bus to avoid signal crosstalk in CANTX from other nearby pins.
