Receiving Data using the Polled Method
Receiving Data using the Interrupt-Driven Method
Follow these steps to configure the UART for polled data reception:
1. Write to the UART Baud Rate High and Low Byte registers to set the desired baud
2. Enable the UART pin functions by configuring the associated GPIO Port pins for
3. Write to the UART Control 1 register to enable Multiprocessor (9-bit) mode functions,
4. Write to the UART Control 0 register to:
5. Check the RDA bit in the UART Status 0 register to determine if the Receive Data
