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
to this register. If this register is allocated to the transmit queue, only write to a transmit buffer p (p = m
× 16 + 15) for the corresponding channel.
