23.5
This section describes the global utilities from a functional perspective.
23.5.1
The PMC is responsible for maintaining the device in various low power modes.
23.5.1.1
MPC8536E supports minimizing the power consumption at several levels.
MPC8536E supports a deep sleep mode where power is removed to a portion of the die.
The PMC can gracefully stop the internal system bus and direct the memory controller to put DDR into
self-refresh (if enabled).
In addition, the PMC controls the external power regulator switch to disable the VDD from a portion of
the die.
