W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 1-0
SID<2:0>: Standard Identifier bits (if EXID = 0)
Extended Identifier bits, EID<20:18> (if EXID = 1).
SRR: Substitute Remote Transmission Request bit
This bit is always ‘1’ when EXID = 1 or equal to the value of RXRTRRO (BnCON<5>) when EXID = 0.
EXIDE: Extended Identifier Enable bit
1 = Received message is an extended identifier frame (SID<10:0> are EID<28:18>)
0 = Received message is a standard identifier frame
Unimplemented: Read as ‘0’
EID<17:16>: Extended Identifier bits
Note 1: These registers are available in Mode 1 and 2 only.

Unimplemented: Read as ‘0’
EXIDE: Extended Identifier Enable bit
1 = Message will transmit extended ID, SID<10:0> bits become EID<28:18>
0 = Received will transmit standard ID, EID<17:0> are ignored
Unimplemented: Read as ‘0’
EID<17:16>: Extended Identifier bits
Note 1: These registers are available in Mode 1 and 2 only.
