data registers, shifter logic, baud rate generator, master/slave control logic, and port control logic.
14.2
This section lists the name and description of all ports including inputs and outputs that do, or may, connect
off chip. The SPIV3 module has a total of four external pins.
14.2.1
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.
