PIC32MX3XX/4XX. The PIC32MX devices offer a total
of nine methods and modes that are organized into two
categories that allow the user to balance power con-
sumption with device performance. In all of the meth-
ods and modes described in this section, power saving
is controlled by software.
25.1
When the CPU is running, power consumption can be
controlled by reducing the CPU clock frequency, lower-
ing the PBCLK, and by individually disabling modules.
These methods are grouped into the following modes:
• FRC Run mode: the CPU is clocked from the FRC
• LPRC Run mode: the CPU is clocked from the
• SOSC Run mode: the CPU is clocked from the
• Peripheral Bus Scaling mode: peripherals are
25.2
The device supports two power-saving modes, Sleep
and Idle, both of which halt the clock to the CPU. These
modes operate with all clock sources, as listed below:
• POSC Idle Mode: the system clock is derived
• FRC Idle Mode: the system clock is derived from
• SOSC Idle Mode: the system clock is derived
• LPRC Idle Mode: the system clock is derived from

25.3
The purpose of all power saving is to reduce power
consumption by reducing the device clock frequency.
To achieve this, low-frequency clock sources can be
selected. In addition, the peripherals and CPU can be
halted or disabled to further reduce power consump-
tion.
25.3.1
Sleep mode has the lowest power consumption of the
device Power-Saving operating modes. The CPU and
most peripherals are halted. Select peripherals can
continue to operate in Sleep mode and can be used to
wake the device from Sleep. See individual peripheral
module sections for descriptions of behavior in Sleep.
Sleep mode includes the following characteristics:
• The CPU is halted.
• The system clock source is typically shut down.
• There can be a wake-up delay based on the

• Some modules can be individually disabled by
and any peripherals that operate from the system
clock source, are halted.
Some peripherals can operate in Sleep using spe-
cific clock sources. This is the lowest power mode
for the device.
