Receiving Data using the Polled Method
The UART is now configured for interrupt-driven data transmission. Because the UART
Transmit Data register is empty, an interrupt is generated immediately. When the UART
Transmit interrupt is detected, the associated interrupt service routine (ISR) performs the
following:
1. Write the UART Control 1 register to select the multiprocessor bit for the byte to be
2. Write the data byte to the UART Transmit Data register. The transmitter automatically
3. Clear the UART Transmit interrupt bit in the applicable Interrupt Request register.
4. Execute the
Follow the steps below to configure the UART for polled data reception:
1. Write to the UART Baud Rate High and Low Byte registers to set an acceptable baud
2. Enable the UART pin functions by configuring the associated GPIO port pins for
