Document Table of Contents SPI Master

The SPI master module (altera_avalon_spi) is a 4-wire, 24-bit width interface.

This module uses the SPI protocol to facilitate the configuration of external converters (for example, ADC, DAC, external clock modules) via a structured register space inside the converter device. The SPI master module is connects to the Nios II processor via the Avalon-MM interconnect. By default, the software does not contain any external converter configuration features but you can use the Platform Designer (Standard) system to implement the feature in the software.

For more details on the SPI master module, refer to chapter 5.
