1.3.1.2.3. SPI Master Module

The SPI master module is a 4-wire, 24-bit width interface that uses the SPI protocol to facilitate the configuration of external converters (for example, ADC, DAC, and external clock modules) via a structured register space provided inside the converter device. The SPI master module connects to the ARM® HPS via the Avalon-MM bridge. The ARM® HPS sends the configuration instructions and data to external converters during the external converter configuration operation. The software instructions to execute external converter configuration via the SPI interface is described in the Reference Design Software section.
