serial port listener

Two independent asynchronous serial I/O ports are provided for the UART unit of the high-efficiency FIFO serial port based on the implementation of b0x (clock frequency: 60 MHz) on the ARM7, each communication port can work in the interrupt or DMA mode. That is, UART can generate an internal interrupt request or DMA re
