27.0
This section describes power-saving features for the
PIC32MX5XX/6XX/7XX family of devices. These
devices offer a total of nine methods and modes,
organized into two categories, that allow the user to
balance power consumption with device performance.
In all of the methods and modes described in this
section, power-saving is controlled by software.
27.1
When the CPU is running, power consumption can be
controlled by reducing the CPU clock frequency,
lowering the PBCLK and by individually disabling
modules. These methods are grouped into the
following categories:
• FRC Run mode: the CPU is clocked from the FRC
• LPRC Run mode: the CPU is clocked from the
• S
In addition, the Peripheral Bus Scaling mode is available
where peripherals are clocked at the programmable
fraction of the CPU clock (SYSCLK).
27.2
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:

27.3
Peripherals and the CPU can be halted or disabled to
further reduce power consumption.
27.3.1
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 the 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 shutdown.
• There can be a wake-up delay based on the
