devices
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
dsPIC33FJ32GP202/204
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
selectively tailor an application’s power consumption
while still maintaining critical application features, such
as timing-sensitive communications.
9.1
dsPIC33FJ32GP202/204 and dsPIC33FJ16GP304
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

9.2
dsPIC33FJ32GP202/204 and dsPIC33FJ16GP304
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 LPRC clock continues to run if the WDT is
• 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
