When configured for SPI, in addition to the normal Sercom pad mapping, the SPI peripheral allows those pads to be assigned to different combinations of DI (data-in), DO (data-out), SCK (clock) and SS (slave select) functions. The SPIXPinOut types represent concrete pad mappings for a given SPI Instance. For slaves, DI is the MOSI function and DO is the MISO function. For masters, DI is the MISO function and DO is the MOSI function. The slave configurations all require an SS pin and are constructed using the enum variants ending with SS. The master confiugrations do not require an SS pin and are constructed using the other variants. The SPI master hardware has support for automatically managing the SS line to enable a slave, but this interface does not expose that functionality. The variant names refer to the Data-in-Data-out configuration that is used to configure the SPI peripheral.
