Transmit Message Object Remote Monitoring
Mode
0 Remote Monitoring mode is disabled.
1 Remote Monitoring mode is enabled for this
transmit message object. The identifier and DLC
code of a remote frame with matching identifier
are copied to this transmit message object in
order to monitor incoming remote frames.
Bit RMM is only available for transmit objects and has
no impact for receive objects.

identifier.
1 This message object uses an extended 29-bit
identifier.

0 The message object is defined as receive
object. If TXRQ = ‘10’, a remote frame with the
identifier of this message object is transmitted.
On reception of a data frame with matching
identifier, the message data is stored in the
corresponding MSGDRn0/MSGDRn4 registers.
1 The message object is declared as transmit
object. If TXRQ = ‘10’, the respective data frame
is transmitted. On reception of a remote frame
with matching identifier, RMTPND and TXRQ
are set to ‘10’.

0000_B - 1XXX_B
DLC contains the number of data bytes associated to
the message object.
Bitfield DLC may be modified by hardware in Remote
Monitoring Mode and in Gateway Mode.
