Modify this register when the TMTRM bit in the corresponding RSCAN0TMSTSp register is set to 0
(no transmit request is present). If this register is linked to a transmit/receive FIFO buffer, do not write
data to this register. If this register is allocated to the transmit queue, only write data to a transmit buffer
p (p = m × 16 + 15) for the corresponding channel.
TMIDE Bit
This bit is used to set the ID format of the message to be transmitted from the transmit buffer.
TMRTR Bit
This bit is used to set the data format of the message to be transmitted from the transmit buffer.
THLEN Bit
When this bit is set to 1, the transmit history data of the transmit message (the label information and the
number and type of the transmit buffer) are stored in the transmit history buffer after transmission is
completed.
TMID[28:0] Bits
These bits are used to set the ID of the message to be transmitted from the transmit buffer.
