3.2.1 UART Interface

The TxD and RxD pins on the PGA450-Q1 device are connected to the 8051W UART. These two pins can be used either for software debugging or for implementing application-specific protocols. For a detailed example of how to use UART with the PGA450-Q1 device, refer to Section 2.3.
