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 connected to the Nios® II processor via the Avalon® -MM interconnect. This module is an optional component because the design only showcases external FMC loopback.
