the structure of the SPI module.
The SPI module allows full-duplex, synchronous, serial communication
among 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.
This subsection describes the operation of the SPI module.
