The slave select pin automatically generates the select signal
at each word transfer. This pin can also be used as a general-
purpose I/O during the SPI transfer without affecting the
SPORT operations.
The SPI clock polarity and phase are configurable through
Bits 13 and 12 of the MODECTRL register. The SPI transfer
using clock phase is shown in Figures 20 and 21.
