Pins P0.0-P2.3 are capable of being assigned to crossbar peripherals.
The crossbar peripherals are assigned in priority order from top to bottom, according to this
diagram.
enabled, the Crossbar should be manually configured to skip the corresponding port pins.
* NSS is only pinned out when the SPI is in 4-wire mode.

Pin Skip
These boxes represent Port pins which can potentially be assigned to a peripheral.
Special Function Signals are not assigned by the crossbar. When these signals are
Pins can be “skipped” by setting the corresponding bit in PnSKIP to ‘1’.
