Detailed Description

ATCA Hardware abstraction layer for SPI over Harmony PLIB.

This code is structured in two parts. Part 1 is the connection of the ATCA HAL API to the physical SPI implementation. Part 2 is the Harmony SPI primitives to set up the interface.

Prerequisite: add SERCOM SPI Master Interrupt support to application in Mplab Harmony 3
