(master) initiates all SPI transfers. During a transfer, the master shifts data out (on the MOSI pin) to the
slave while simultaneously shifting data in (on the MISO pin) from the slave. Although the SPI interface
supports simultaneous data exchange between master and slave, the modem SPI protocol only uses data
exchange in one direction at a time. The SPSCK 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).
