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 7-5
bit 4
bit 3
bit 2
bit 1-0
SID2:SID0: Standard Identifier bits (if EXID = 0)
Extended Identifier bits EID20:EID18 (if EXID = 1).
SRR: Substitute Remote Transmission Request bit (only when EXID = 1)
1 = Remote transmission request occurred
0 = No remote transmission request occurred
EXID: Extended Identifier Enable bit
1 = Received message is an extended identifier frame (SID10:SID0 are EID28:EID18)
0 = Received message is a standard identifier frame
Unimplemented: Read as ‘0’
EID17:EID16: Extended Identifier bits
Note 1: These registers are available in Mode 1 and 2 only.
