Function Registers
This module contains all PMU relevant registers, which
are needed to control and monitor the PMU.
PMU-PCU
Power Control Unit of the PMU
This block is responsible for controlling all power
related actions within the PGU Module.It also contains
all regulator related diagnosis like under- and
overvoltage detection, overcurrent and short circuit
diagnoses.

PMU
This block is responsible for controlling all Wake-up
related actions within the PMU Module.
PMU-CMU
Cyclic Management Unit of the
PMU
This block is responsible for controlling all actions
within cyclic mode.
PMU-RMU
Reset Management Unit of the PMU This block generates resets triggered by the PMU like
undervoltage or short circuit reset, and passes all resets
to the relevant modules and their register. A reset status
register with every reset source is available.
