3.10. APB bridge

The AHB-APB bridge is an AHB slave, providing an interface between the high-speed AHB domain and the low-power APB domain. Read and write transfers on the AHB are converted into corresponding transfers on the APB through a master interface. Because the APB is not pipelined, wait states are added during transfers to and from the APB when the AHB is required to wait for the APB protocol. The default configuration is 16 slots.

In this release of ADK there are two versions of the APB bridge.
