8.2.3 Voltage Regulator

The PIC32CM SG00 internal main voltage regulators have three modes, controlled by the Power Manager (PM).

Enabled mode: This is the default mode when CPU and peripherals are running.
Low-Power mode: This is the mode when CPU and peripherals are in Standby, Backup, or Hibernate modes.
Disabled mode: When the chip is in Backup mode, the internal regulators (VDDCORE_SW and VDDCORE_RAM) are off, the VDDCORE_SW core power domain is off. The VDDCORE_BU backup domain is powered by the backup regulator (LPVREGC).
