概述
UART0: U0TXD, U0RXD, MTDO(U0RTS), MTCK(U0CTS)
UART1: GPIO2(U1TXD)
Downloading: U0TXD+U0RXD or GPIO2+U0RXD
Communicating: UART0: U0TXD, U0RXD, MTDO(U0RTS), MTCK(U0CTS)
Debugging: UART1_TXD (GPIO2) can be used to print debugging information.
By default, UART0 will output some printed information when the device is powered on and is booting up. If this issue exerts influence on some
specific applications, users can exchange the inner pins of UART when initializing, that is to say, exchange U0TXD, U0RXD with U0RTS, U0CTS
