An external master drives the Slave Select input pin, SS/P1[4], low to select the SPI
module as a slave. If SS/P1[4] has not been driven low, then the slave SPI unit is not
active and the MOSI/P1[5] port can also be used as an input port pin.
CPHA and CPOL control the phase and polarity of the SPI clock.
Figure 18
and
Figure 19
show the four possible combinations of these two bits.

Description
SPIE
If both SPIE and ES are set to one, SPI interrupts are enabled.
SPE
SPI enable bit. When set enables SPI.
DORD
Data transmission order. 0 = MSB first; 1 = LSB first in data
transmission.
MSTR
Master/slave select. 1 = master mode, 0 = slave mode.
CPOL
Clock polarity. 1 = SCK is high when idle (active LOW), 0 = SCK is
low when idle (active HIGH).
CPHA
Clock Phase control bit. 1 = shift triggered on the trailing edge of
the clock; 0 = shift triggered on the leading edge of the clock.
SPR1
SPI Clock Rate Select bit 1. Along with SPR0 controls the SCK
rate of the device when a master. SPR1 and SPR0 have no effect
on the slave. See
Table 32
below.
SPR0
SPI Clock Rate Select bit 0. Along with SPR1 controls the SCK
rate of the device when a master. SPR1 and SPR0 have no effect
on the slave. See
Table 32
below.
