C8051F020中的UART1串口通信测试

c8051f020串口实验程序，UART1工作于中断模式-// This program configures UART1 to operate in interrupt mode, showing an example of a string transmitter and a string receiver. These strings are assumed to be NULL-terminated

This program demonstrates how to configure the C8051F020 to write to and read from the UART interface. The program reads a word using the UART1 interrupts and outputs that word to the screen, with all characters in uppercase
