Transmit data
TxD
When the value of the SCTDSR register and the number of transmit data match, transmit
operation stops. Setting the TSIE bit (interrupt enable bit) allows the generation of an interrupt
and activation of DMAC.
Figure 18.5 shows an example of the operation for transmit data stop function.
