10.0
The
PIC24EPXXXGU810/814 devices provide the ability
to
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.
dsPIC33EPXXXMU806/810/814
PIC24EPXXXGU810/814 devices can manage power
consumption in four 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 selec-
tively tailor an application’s power consumption while
still maintaining critical application features, such as
timing-sensitive communications.
10.1
The
PIC24EPXXXGU810/814 devices allow 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
(OSCCON<10:8>). The process of changing a system
clock during operation, as well as limitations to the
process, are discussed in more detail in

10.2
The
PIC24EPXXXGU810/814 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 assembler 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.
10.2.1
The following occur in Sleep mode:
• The system clock source is shut down. If an

• The Fail-Safe Clock Monitor does not operate,
• The LPRC clock continues to run in Sleep mode if
• The WDT, if enabled, is automatically cleared
• Some device features or peripherals can continue
• Any peripheral that requires the system clock
The device wakes up from Sleep mode on any of the
these events:
• Any interrupt source that is individually enabled
• Any form of device Reset
• A WDT time-out
On wake-up from Sleep mode, the processor restarts
with the same clock source that was active when Sleep
mode was entered.
