FlexIO for Half duplex UART

      虽然目前NXP的很多MCU都带了丰富的UART资源，但是在某些特地的情况下或个别芯片，UART数量还是有一定的局限性。现在NXP很多的MCU也携带有FlexIO模块，那么我们就可以利用FlexIO来扩展更多的UART，SDK中有相应的代码，这些代码是支持全双工的，需要使用至少两个timer和两个shifter设计一个UART, 在实际使用中很多时候是使用半双工通信的，本文是基于SDK FlexIO的例程来设计基于一个timer和一个shifter的半双工UART，最大限度扩展UART数量，设计4个半双工的UART，本文设计验证平台为FRDEM-KE15Z和SDK_2.6.0_MKE15Z256xxx7。

    希望能给需要的使用者提供种扩展尽可能多UART的方法。

Best Regards,

Fred Fu
