Transmitting Data Using the Polled Method
Start
Follow the steps below to transmit data using the polled method of operation:
1. Write to the baud rate generator constant (BCNST) register, address
2. Write a 0 to bit 6 of the P01M register.
3. Write to the UART control register (UCTL) to:
4. Check the Transmit Status register bit, UST[2], to determine if the Transmit Data
5. Write the data byte to the UART Transmit Data register,

(a) Set the transmit enable bit, UCTL[7], to enable the UART for data transmission.
(b) If parity is appropriate, set the parity enable bit, UCTL[4] to 1 and select either
