CPOL: Clock Polarity
0 = The inactive state value of SPCK is logic level zero.
1 = The inactive state value of SPCK is logic level one.
CPOL is used to determine the inactive state value of the serial clock (SPCK). It is used with NCPHA to produce a
desired clock/data relationship between master and slave devices.
NCPHA: Clock Phase
0 = Data is changed on the leading edge of SPCK and captured on the following edge of SPCK.
1 = Data is captured on the leading edge of SPCK and changed on the following edge of SPCK.
NCPHA determines which edge of SPCK causes data to change and which edge causes data to be captured. NCPHA
is used with CPOL to produce a desired clock/data relationship between master and slave devices.
BITS: Bits Per Transfer
The BITS field determines the number of data bits transferred. Reserved values should not be used.
