SMP
SMP: SPI Data Input Sample Phase bit
SPI Master mode:
1 = Input data sampled at end of data output time
0 = Input data sampled at middle of data output time
SPI Slave mode:
SMP must be cleared when SPI is used in Slave mode
CKE: SPI Clock Edge Select bit
SPI mode, CKP = 0:
1 = Data stable on rising edge of SCK
0 = Data stable on falling edge of SCK
SPI mode, CKP = 1:
1 = Data stable on falling edge of SCK
0 = Data stable on rising edge of SCK
D/A: Data/Address bit
