TECHNICAL DATA
8.5.1 Serial Peripheral Control
SPIE — Serial Peripheral Interrupt Enable
0 = SPI interrupt disabled
1 = SPI interrupt enabled
SPE — Serial Peripheral System Enable
0 = SPI off
1 = SPI on
DWOM — Port D Wired-OR Mode
DWOM affects all six port D pins.
0 = Normal CMOS outputs
1 = Open-drain outputs
MSTR — Master Mode Select
0 = Slave mode
1 = Master mode
CPOL — Clock Polarity
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.
CPHA — Clock Phase
The clock phase bit, in conjunction with the CPOL bit, controls the clock-data relation-
ship between master and slave. The CPHA bit selects one of two different clocking
SPR1 and SPR0 — SPI Clock Rate Selects
These two serial peripheral rate bits select one of four baud rates to be used as SCK
if the device is a master; however, they have no effect in the slave mode.
