RTR — Remote Frame
This bit specifies if Remote Frames are accepted into the FIFO if they match the target
ID.
1 = Remote Frames can be accepted and data frames are rejected
0 = Remote Frames are rejected and data frames can be accepted
IDE — Extended Frame
Specifies whether extended or standard frames are accepted into the FIFO if they match
the target ID.
1 = Extended frames can be accepted and standard frames are rejected
0 = Extended frames are rejected and standard frames can be accepted
RXIDA — Rx Frame Identifier (Format A)
Specifies an ID to be used as acceptance criteria for the FIFO. In the standard frame
format, only the 11 most significant bits (29 to 19 ) are used for frame identification. In
the extended frame format, all bits are used.
RXIDB_0, RXIDB_1 — Rx Frame Identifier (Format B)
Specifies an ID to be used as acceptance criteria for the FIFO. In the standard frame
format, the 11 most significant bits (a full standard ID) (29 to 19 and 13 to 3 ) are used
for frame identification. In the extended frame format, all 14 bits of the field are
compared to the 14 most significant bits of the received ID.
RXIDC_0, RXIDC_1, RXIDC_2, RXIDC_3 — Rx Frame Identifier (Format C)
Specifies an ID to be used as acceptance criteria for the FIFO. In both standard and
extended frame formats, all 8 bits of the field are compared to the 8 most significant bits
of the received ID.
