9.0
The PIC24FJ256GA110 family of devices provides the
ability to manage power consumption by selectively
managing clocking to the CPU and the peripherals. In
general, a lower clock frequency and a reduction in the
number of circuits being clocked constitutes lower
consumed power. All PIC24F devices manage power
consumption in four different ways:
• Clock frequency
• Instruction-based Sleep and Idle modes
• Software controlled Doze mode
• Selective peripheral control in software
Combinations of these methods can be used to
selectively tailor an application’s power consumption,
while still maintaining critical application features, such
as timing-sensitive communications.
9.1
PIC24F devices allow for a wide range of clock
frequencies to be selected under application control. If
the system clock configuration is not locked, users can
choose low-power or high-precision oscillators by simply
changing the NOSC bits. The process of changing a
system clock during operation, as well as limitations to
the process, are discussed in more detail in
“Oscillator
9.2
PIC24F devices have two special power-saving modes
that are entered through the execution of a special
PWRSAV instruction. Sleep mode stops clock operation
and halts all code execution; Idle mode halts the CPU
and code execution, but allows peripheral modules to
continue operation. The assembly syntax of the
PWRSAV instruction is shown in

Sleep and Idle modes can be exited as a result of an
enabled interrupt, WDT time-out or a device Reset.
When the device exits these modes, it is said to
“wake-up”.
9.2.1
Sleep mode has these features:
• The system clock source is shut down. If an
• The device current consumption will be reduced
• The Fail-Safe Clock Monitor does not operate
• The LPRC clock will continue to run in Sleep
• The WDT, if enabled, is automatically cleared
• Some device features or peripherals may
Additional power reductions can be achieved by
disabling the on-chip voltage regulator whenever Sleep
mode is invoked. This is done by clearing the PMSLP
bit (RCON<8>). Disabling the regulator adds an addi-
tional delay of about 190 s to the device wake-up
time. It is recommended that applications not using the
voltage regulator leave the PMSLP bit set. For addi-
tional details on the regulator and Sleep mode, see
Section 25.2.5 “Voltage Regulator Standby
The device will wake-up from Sleep mode on any of
these events:
• On any interrupt source that is individually
• On any form of device Reset
• On a WDT time-out
On wake-up from Sleep, the processor will restart with
the same clock source that was active when Sleep
mode was entered.
