Unit (PGU)
VDDC
VDDEXT
PMU-SFR
PMU-PCU
Voltage regulator for VDDEXT to
supply external modules (e.g.
Sensors)
This voltage regulator is a dedicated supply for external
modules and can also be used for cyclic sense operations
(e.g. with hall sensor).
All Extended Special Function
registers that are relevant to the
PMU.
This module contains all registers needed to control and
monitor the PMU.
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 diagnostics such as undervoltage and
overvoltage detection as well as overcurrent and short
circuit diagnostics.
PMU-WMU
PMU-CMU
PMU-RMU
Wake-Up Management Unit of the This block is responsible for controlling all wake-up related
PMU actions within the PMU Module.
Cyclic Management Unit of the PMU This block is responsible for controlling all actions in cyclic
mode.
Reset Management Unit of the PMU This block generates resets triggered by the PMU such as
undervoltage or short circuit reset, and passes all resets to
the relevant modules and their register.
