The
dsPIC33FJ32(GP/MC)101/102/104 devices provide
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. Devices can 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 selec-
tively tailor an application’s power consumption while
still maintaining critical application features, such as
timing-sensitive communications.
9.1
dsPIC33FJ16(GP/MC)101/102 and dsPIC33FJ32(GP/
MC)101/102/104 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 NOSCx 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
Configuration”.

9.2
dsPIC33FJ16(GP/MC)101/102 and dsPIC33FJ32(GP/
MC)101/102/104 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.

The following occur in Sleep mode:
• The system clock source is shut down. If an
• The device current consumption is reduced to a
• 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 may continue
• Any peripheral that requires the system clock
The device will wake-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.
