15.6.6 Continuous transmission procedure
shift operation. The transmit timing of the UARTAn transmit shift register can be judged from the transmission enable
interrupt request signal (INTUAnT).
transfer.
UARTAn can write the next transmit data to the UAnTX register when the UARTAn transmit shift register starts the
An efficient communication rate is realized by writing the data to be transmitted next to the UAnTX register during
Caution When initializing transmissions during the execution of continuous transmissions, make sure
that the UAnSTR.UAnTSF bit is 0, then perform the initialization. Transmit data that is initialized
when the UAnTSF bit is 1 cannot be guaranteed.
