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 15-10 EID<5:0>: Extended Identifier bits
bit 9 RTR: Remote Transmission Request bit
1 = Message will request remote transmission
0 = Normal message
bit 8 RB1: Reserved Bit 1
User must set this bit to ‘0’ per CAN protocol.
bit 7-5 Unimplemented: Read as ‘0’
bit 4 RB0: Reserved Bit 0
User must set this bit to ‘0’ per CAN protocol.
