PIC32MK UART引脚设置有问题

问候语！我正在使用多UART OPIC32 MK1024GPD064。问题是1 RX引脚上的收入数据导致数据被从多个引脚接受——它触发多个中断，并且许多UART接收相同的数据。这是我的密码：知道我做错了什么吗？谢谢！

    Greetings! I`m using multiple UARTs on PIC32MK1024GPD064. The problem is income data on 1 RX pin cause the data to be accepted from multiple pins - it triggers multiple interrupts and many UARTs receive the same data. Here is my code:
