Upper Byte:
U-0 U-0 U-0 R/W-x R/W-x R/W-x R/W-x R/W-x
— — —SID<10:6>
bit 15 bit 8
Lower Byte:

SID<5:0> SRR RXIDE
bit 7 bit 0
bit 15-13 Unimplemented: Read as ‘0’
bit 12-2 SID<10:0>: Standard Identifier bits
bit 1 SRR: Substitute Remote Request bit (Only when RXIDE = 1)
1 = Remote transfer request occured
0 = No remote transfer request occured
bit 0 RXIDE: Extended Identifier Flag bit
1 = Received message is an extended data frame, SID<10:0> are EID<28:18>
0 = Received message is a standard data frame
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
