Systems and methods are described for a flexible and selectable power management interface. The flexible and selectable power management interface can provide multiple power management interfaces which are selectable based on a selected processor IP core, a selected power management controller, and a variety of factors. The flexible and selectable power management interface can be a direct handshake hardware interface, a memory-mapped bus interface, or a combination of the direct handshake hardware interface and the memory-mapped bus interface.
