device initiates all SPI data transfers. During a transfer, the master shifts data out (on the MOSI1 pin) to
the slave while simultaneously shifting data in (on the MISO1 pin) from the slave. The transfer effectively
exchanges the data that was in the SPI shift registers of the two SPI systems. The SPSCK1 signal is a clock
output from the master and an input to the slave. The slave device must be selected by a low level on the
slave select input (SS1 pin). In this system, the master device has configured its SS1 pin as an optional
slave select output.
