19.3.1 Power Modes

The power modes and power management of different modules of the PIC32CX-BZ6 are shown in the following table.

Table 19-1. Power Modes and Power Management Features
Functions	Device Power Modes
Functions	Run	Idle	SleepWalking/Dream⁽¹⁾	Standby Sleep	Deep Sleep	Extreme Deep Sleep

FlexRAM (SRAM, retention part)	ON	Idle	On Demand	Retention Mode	Retention Mode (On Demand)	OFF
XTAL(16 MHz)	ON	ON	ON	ON	OFF	OFF

LPRC	ON	ON	ON	ON	ON	OFF
SPLL	ON	ON	On Demand	OFF	OFF	OFF
SOSC	ON	ON	ON	ON	ON	OFF

Note:

Dream (Sleep Walking) is not a mode by itself but is a companion mode to the Standby Sleep mode. This mode cannot be entered directly through a software command.

All transitions from the Run state to any of the low-power states are simply initiated by the WFI command from the CPU. However, prior to initiating the WFI command firmware must perform the operation in 18.3.1.1.
