SPI Master Core Specification
[attachment=55336]
Introduction
This document provides specifications for the SPI (Serial Peripheral Interface) Master
core. Synchronous serial interfaces are widely used to provide economical board-level
interfaces between different devices such as microcontrollers, DACs, ADCs and
other. Although there is no single standard for a synchronous serial bus, there are
industry-wide accepted guidelines based on two most popular implementations:
SPI (a trademark of Motorola Semiconductor)
Microwire/Plus (a trademark of National Semiconductor)
Many IC manufacturers produce components that are compatible with SPI and
Microwire/Plus.
The SPI Master core is compatible with both above-mentioned protocols as master
with some additional functionality. At the hosts side, the core acts like a WISHBONE
compliant slave device.
