The SPCR contains parameters for configuring the SPI. The register can be read or
written at any time.
CPOL is used to determine the inactive state of the serial clock (SCK). It is used with
CPHA to produce a desired clock/data relationship between master and slave devices.
CPHA determines which edge of SCK causes data to change and which edge causes
data to be captured. CPHA is used with CPOL to produce a desired clock/data rela-
tionship between master and slave devices.
0 = SPI interrupts disabled.
1 = SPI interrupts enabled.
0 = SPI is disabled.
1 = SPI is enabled.
0 = Outputs have normal CMOS drivers.
1 = Pins designated for output by MDDR have open-drain drivers, regardless of
0 = SPI is a slave device.
1 = SPI is system master.
0 = The inactive state value of SCK is logic level zero.
1 = The inactive state value of SCK is logic level one.
0 = Data captured on the leading edge of SCK and changed on the trailing edge of
1 = Data is changed on the leading edge of SCK and captured on the trailing edge
