SPICLK pin is the clock output and input for the master and slave modes, respectively.
The SPI clock generator will start following a write to the master devices SPI data register.
The written data is then shifted out of the MOSI pin on the master device into the MOSI
pin of the slave device. Following a complete transmission of one byte of data, the SPI
clock generator is stopped and the SPIF flag is set. An SPI interrupt request will be
generated if the SPI Interrupt Enable bit (SPIE) and the SPI interrupt enable bit, ES3, are
both set.
An external master drives the Slave Select input pin, SS LOW to select the SPI module as
a slave. If SS has not been driven LOW, then the slave SPI unit is not active and the MOSI
pin can also be used as an input port pin.
CPHA and CPOL control the phase and polarity of the SPI clock. Figure 24 and Figure 25
show the four possible combinations of these two bits.

SPIE
If both SPIE and ES3 are set to one, SPI interrupts are enabled.

SPEN
SPI enable bit. When set enables SPI.
5
DORD
Data transmission order. 0 = MSB first; 1 = LSB first in data
transmission.
4
MSTR
Master/slave select. 1 = master mode, 0 = slave mode.
3
CPOL
Clock polarity. 1 = SPICLK is high when idle (active LOW),
0 = SPICLK is low when idle (active HIGH).
