2.1.2. AHB to APB bridge

The internal memory controllers of the AHB MC use the AMBA3 APB protocol for their configuration ports. To enable the AHB MC to externally function as an AHB device, the APB configuration ports are connected to an AHB to APB bridge. The bridge converts incoming AHB transfers from the configuration port to the APB transfers that the internal memory controllers require. This bridge is part of the PrimeCell infrastructure components, part BP127.

See AHB to APB bridge operation for more information.
