The SPI interface has four pins: SPICLK, MOSI, MISO, and SS:
SPICLK, MOSI and MISO are typically tied together between two or more SPI
devices. Data ows from master to slave on MOSI (Master Out Slave In) pin and
ows from slave to master on MISO (Master In Slave Out) pin. The SPICLK signal
is output in the master mode and is input in the slave mode. If the SPI system is
disabled, i.e. SPEN (SPCTL.6) = 0 (reset value), these pins are congured for port
functions.
SS is the optional slave select pin. In a typical conguration, an SPI master asserts
one of its port pins to select one SPI device as the current slave. An SPI slave
device uses its SS pin to determine whether it is selected.
