A clock phase control bit (CPHA) and a clock polarity control bit (CPOL)
in the SP0CR1 register select one of four possible clock formats to be
used by the SPI system. The CPOL bit simply selects non-inverted or
inverted clock. The CPHA bit is used to accommodate two
fundamentally different protocols by shifting the clock by one half cycle
or no phase shift.
