Field Description
REM 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
EXT 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 (3 to 13) 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) (3 to 13)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.
