When the clock polarity bit is cleared and data is not being
transferred, the SCK pin of the master device has a steady state low
value. When CPOL is set, SCK idles high. Refer to
8.5 Clock Phase and Polarity
The clock phase bit, in conjunction with the CPOL bit, controls the
clock-data relationship between master and slave. The CPHA bit
selects one of two different clocking protocols. Refer to
and
These two bits select the SPI clock (SCK) rate when the device is
configured as master. When the device is configured as slave, these
bits have no effect. Refer to
