12.3.4.10. Motorola SPI format with SPO=0, SPH=0
In the case of a single word transmission, after all bits of the data word have been transferred, the SSPFSSOUT line is
returned to its idle HIGH state one SSPCLKOUT period after the last bit has been captured.
However, in the case of continuous back-to-back transmissions, the SSPFSSOUT signal pulse HIGH between each data
word transfer. This is because the slave select pin freezes the data in its serial peripheral register and does not permit it
to be altered if the SPH bit is logic zero. Therefore, the master device must raise the SSPFSSIN pin of the slave device
between each data transfer to enable the serial peripheral data write. On completion of the continuous transfer, the
SSPFSSOUT pin is returned to its idle state one SSPCLKOUT period after the last bit has been captured.
