There are many power islands in the LPD and FPD. The power islands are shown in the device power diagram. The PLM firmware controls the device-level power. The PSM firmware controls the power islands in the LPD and FPD subsystems. The OS software can write to the PMC and PSM global registers to request power island state changes. For PS power request, see the Service Requests to PSM Firmware section.

For power-down requests, the firmware alerts and manages the subsystems and interconnect before a power-down.
