16.6.2 UART transmission
started by writing transmit data to the UAnTX register. The start bit, parity bit, and stop bit are automatically added.

of the UAnTX register to the UARTAn transmit shift register, and the contents of the UARTAn transmit shift register are
output to the TXDAn pin.
Transmission is enabled by setting the UAnCTL0.UAnPWR and UAnCTL0.UAnTXE bits to 1, and transmission is
Since the CTS (transmit enable signal) input pin is not provided in UARTAn, use a port to check that reception is
The data in the UAnTX register is transferred to the UARTAn transmit shift register upon the start of transmission.
A transmission enable interrupt request signal (INTUAnT) is generated upon completion of transmission of the data
Writing the next transmit data to the UAnTX register is enabled after the INTUAnT signal is generated.
