EID: Extended Identifier bits <7:0>
These bits hold the least significant eight bits of the Extended Identifier for the received message
Unimplemented: Reads as ‘0’
RTR: Extended Frame Remote Transmission Request bit
(valid only when RXBnSIDL.IDE = ‘1’)
1 = Extended Frame Remote Transmit Request Received
0 = Extended Data Frame Received
RB1: Reserved Bit 1
RB0: Reserved Bit 0
DLC: Data Length Code bits <3:0>
Indicates number of data bytes that were received
RBnD7:RBnD0: Receive Buffer n Data Field Bytes m
Eight bytes containing the data bytes for the received message
