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
bit 7-5
SID: Standard Identifier bits <2:0>
These bits contain the three least significant bits of the Standard Identifier for the received message
bit 4
SRR: Standard Frame Remote Transmit Request bit (valid only if IDE bit = ‘0’)
1
= Standard Frame Remote Transmit Request Received
0
= Standard Data Frame Received
bit 3
IDE: Extended Identifier Flag bit
This bit indicates whether the received message was a Standard or an Extended Frame
1
= Received message was an Extended Frame
0
= Received message was a Standard Frame
bit 2
Unimplemented: Reads as ‘0’
bit 1-0
EID: Extended Identifier bits <17:16>
These bits contain the two most significant bits of the Extended Identifier for the received message
