Table 13-70 lists the CIR interface 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 in CIR mode. (3) | 0 |
| SD | UART[0-5]_RTSn | O | SD mode is used to configure the transceivers.(4) | 1 |
For more information about device level signals (pull-up/down resistors, buffer type, multiplexing and others), see tables Pin Attributes and Pin Multiplexing in the device-specific Data sheet.
