1、功能说明

    该测例演示了USARTy与USARTz间实现串行IrDA低功耗模式红外解码功能的基础通信。
    首先，USARTy发送TxBuffer1数据至USARTz，USARTz通过中断接收数据存至RxBuffer1。
    随后，比较接收数据与发送数据，比较结果存入TransferStatus变量。

4、注意事项

1. Function description

    This test example demonstrates the basic communication between USARTy and USARTz to realize the infrared 
    decoding function of serial IrDA low power consumption mode.
    First, USARTy sends TxBuffer1 data to USARTz, and USARTz receives data through interrupt and stores it in RxBuffer1.
    Subsequently, compare the received data with the sent data, and the result of the comparison is stored in the 
    TransferStatus variable.
