Power management unit (PMU) sequencer

摘要

A technique to use a power management unit (PMU) sequencer to control switching of a plurality of functional modules between two or more power modes. The PMU sequencer sequences through a hierarchical order of turn-on and turn-off sequences based on dependencies established for each of the functional modules. In addition to the dependencies, turn-on and turn-off delay times are established for each of the functional modules.
