UARTAn can write the next transmit data to the UAnTX register when the UARTAn transmit shift register starts the shift
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.
