MCU_UART[0-1] | ||||
RX | MCU_UART[0-1]_RXD | I | Serial data input | HiZ |
TX | MCU_UART[0-1]_TXD | O | Serial data output | 1 |
DIR | MCU_UART[0-1]_RTS | O | RS-485 Direction | 1 |
UART[0-6] | ||||
RX | UART[0-6]_RXD | I | Serial data input | HiZ |
TX | UART[0-6]_TXD | O | Serial data output | 1 |
DIR | UART[0-6]_RTSn | O | RS-485 Direction | 1 |
