The AHB-Lite to SPI Bridge is used to translate 32-bit AHB-Lite Writes and Reads to Writes and Reads over a SPI interface. A custom 32-bit protocol is implemented on the SPI bus.
The AHB-Lite to SPI Bridge has two AHB-Lite Slave component interfaces; one for access to the control/status registers (Register Interface), and another for access to the external SPI device (External Interface). The Bridge also has a SPI interface that operates exclusively as a SPI Master component device.
