Pins P0.0-P2.7
The crossbar peripherals are assigned in priority order from top to bottom, according to this
diagram.
the Crossbar should be manually configured to skip the corresponding port pins.
Notes:
1. P2.4-P2.7 are only available in certain packages.
2. NSS is only pinned out when the SPI is in 4-wire mode.

Function
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 enabled,
Pins can be “skipped” by setting the corresponding bit in PnSKIP to ‘1’.
