+Example Description
+
+This example describes how to use UART to communicate with PC.
+
+Required Components:
+    USBtoTTL adapter
+
+Connect to PC
+ - Connect Ground: connect to GND pin via USBtoTTL adapter
+ - Use UART0
+	GPIOA_18 as UART0_RX connect to TX of USBtoTTL adapter
+	GPIOA_23 as UART0_TX connect to RX of USBtoTTL adapter
+
+Open Super terminal or teraterm and 
+set baud rate to 38400, 1 stopbit, no parity, no flow contorl.
+
+This example shows:
+1. The RX data ready interrupt service routine is used to receive characters from the PC, and then loopback them to the PC.
+2. The TX done interrupt service routine will send a prompt string "8195a$" to the PC.
