SPI to AHB Bridge

Status:

Available

The SPI2AHB bridge is an SPI slave that provides a link between a SPI bus (that consists of two data signals, one clock signal and one select signal) and AMBA AHB.

Overview

The SPI to AHB bridge is an SPI slave that provides a link between a SPI bus (that consists of two data signals, one clock signal and one select signal) and AMBA AHB. On the SPI bus the slave acts as an SPI memory device where accesses to the slave are translated to AMBA accesses. The core can translate SPI accesses to AMBA byte, half-word or word accesses. The access size to use is configurable via the SPI bus.
