13.2
This section lists the name and description of all ports including inputs and outputs that do, or may, connect
off chip. The SPI module has a total of four external pins.
13.2.1
This pin is used to transmit data out of the SPI module when it is configured as a master and receive data
when it is configured as slave.
13.2.2
This pin is used to transmit data out of the SPI module when it is configured as a slave and receive data
when it is configured as master.
