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. All SPI interrupts can be serviced by the CPU.
The following paragraphs describe the operation of the SPI module.
