I'm reasonably confident the answer to this question is "yes", but I'd like another pair of eyes (or brains) on it before we commit it to the PCB.
The 28035 is receiving data from a slave device - the 28035 is the SPI master. The only SPI pins we actually need are the clock and the SOMI pins. We don't need the SIMO pin (the slave is not receiving any data from the 28035) and we also don't need the enable (the slave device is permanently enabled). We'd like to use the SIMO and enable pins as GPIOs. Is the SPI peripheral still going to be happy if we configure the SIMO and enable pins as GPIOs? (They're both output pins from the SPI peripheral so I'm thinking the SPI peripheral block won't know and won't care. I think.)
Thanks.
