The SPI module allows full-duplex, synchronous, serial communication
between the MCU and peripheral devices, including other MCUs.
Software can poll the SPI status flags or SPI operation can be interrupt-
driven.
If a port bit is configured for input, then an internal pullup device may be
enabled for that port bit.
