Transmit Object Remote Monitoring
0
Remote monitoring is disabled:
Identifier, IDE bit, and DLC of message object
n remain unchanged upon the reception of a
matching remote frame.
1
Remote monitoring is enabled:
Identifier, IDE bit, and DLC of a matching
remote frame are copied to transmit object n in
order to monitor incoming remote frames.
Bit RMM applies only to transmit objects and has no
effect on receive objects.
SDT
22
rw
Single Data Transfer
If SDT = 1 and message object n is not a FIFO base
object, then MSGVAL is reset when this object has
taken part in a successful data transfer (receive or
transmit).
If SDT = 1 and message object n is a FIFO base
object, then MSGVAL is reset when the pointer to the
current object CUR reaches the value of SEL in the
FIFO/Gateway Pointer Register.
With SDT = 0, bit MSGVAL is not affected.
STT
23
rw
Single Transmit Trial
If this bit is set, then TXRQ is cleared on
transmission start of message object n. Thus, no
transmission retry is performed in case of
transmission failure.

Data Length Code
Bit field determines the number of data bytes for
message object n. Valid values for DLC are 0 to 8.
A value of DLC > 8 results in a data length of 8 data
bytes, but the DLC code is not truncated upon
reception or transmission of CAN frames.
