Table 13-64 lists the RS-485 interface input/output (I/O) signals.
| Module Pin | Device Level Signal | I/O(1) | Description | Module Pin Reset Value(2) |
|---|---|---|---|---|
| UART[0-5] | ||||
| RX | UART[0-5]_RXD | I | Serial data input | HiZ |
| TX | UART[0-5]_TXD | O | Serial data output | 1 |
| DIR | UART[0-5]_RTSn | O | RS-485 Direction | 1 |
