Table 23-1 lists the external signals of one instance of the SPI and describes the function of each. The SPI signals for all four instances are selected in the IOC module through the IOCFGn registers. For more information on configuration of DIOs, see Chapter 400.
Signal Name | Pin Number | Pin Type(1) | Description |
---|---|---|---|
SPIn_CLK | Assigned in the I/O Controller | I/O | SPI clock Master mode: CLK is an output Slave mode: CLK is an input |
SPIn_CS | I/O | SPI chip select Master mode: CS is an output Slave mode: CS is an input | |
SPIn_TX | O | SPI TX Output Master mode: TX drives MOSI Slave mode: TX drives MISO | |
SPIn_RX | I | SPI RX Input Master mode: RX drives MISO Slave mode: RX drives MOSI |
