3.5.5 Serial Peripheral Interface Module Signals
These signals are used by the SPI module and may also be configured
to be discrete I/O signals.
3.5.5.1 Master Out/Slave In (MOSI)
This signal is the serial data output from the SPI in master mode and the
serial data input in slave mode.
3.5.5.2 Master In/Slave Out (MISO)
This signal is the serial data input to the SPI in master mode and the
serial data output in slave mode.
3.5.5.3 Serial Clock (SCK)
The serial clock synchronizes data transmissions between master and
slave devices. SCK is an output if the SPI is configured as a master. SCK
is an input if the SPI is configured as a slave.
3.5.5.4 Slave Select (SS)
This I/O signal is the peripheral chip select signal in master mode and is
an active-low slave select in slave mode.
3.5.6 Serial Communications Interface Module Signals
These signals are used by the two SCI modules.
3.5.6.1 Receive Data (RXD1 and RXD2)
These signals are used for the SCI receiver data input and are also
available for GPIO when not configured for receiver operation.
