Table 12-448 lists the CIR interface I/O signals.
Module Pin | Device Level Signal | I/O(1) | Description | Module Pin Reset Value(2) |
---|---|---|---|---|
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 in CIR mode. (3) | 0 |
SD | MCU_UART[0-1]_RTS | O | SD mode is used to configure the transceivers.(4) | 1 |
UART[0-6] | ||||
RX | UART[0-6]_RXD | I | Serial data input | HiZ |
TX | UART[0-6]_TXD | O | Serial data output in CIR mode. (3) | 0 |
SD | UART[0-6]_RTSn | O | SD mode is used to configure the transceivers.(4) | 1 |
