Work around 2:
Instead of executing a PWRSAV #0 instruction to
put the device into Sleep mode, perform a clock
switch to the 512 kHz Low-Power RC (LPRC)
Oscillator with a 64:1 postscaler mode. This
enables the device to operate at 0.002 MIPS,
thereby significantly reducing the current
consumption of the device. Similarly, instead of
using an interrupt to wake-up the device from
Sleep mode, perform another clock switch back to
the original oscillator source to resume normal
operation. Depending on the device, refer to
Section 7. “Oscillator” (DS70054) or Section
29. “Oscillator” (DS70268) in the “dsPIC30F
Family Reference Manual” (DS70046) for more
details on performing a clock switch operation.
Work around 3:
Instead of executing a PWRSAV #0 instruction to
put the device into Sleep mode, perform a clock
switch to the 32 kHz Low-Power (LP) Oscillator
with a 64:1 postscaler mode. This enables the
device to operate at 0.000125 MIPS, thereby
significantly reducing the current consumption of
the device. Similarly, instead of using an interrupt
to wake-up the device from Sleep mode, perform
another clock switch back to the original oscillator
source to resume normal operation. Depending on
the device, refer to Section 7. “Oscillator”
(DS70054) or Section 29. “Oscillator”
(DS70268) in the “dsPIC30F Family Reference
Manual” (DS70046) for more details on performing
a clock switch operation.
Note: The above work around is recommended
for users for whom application hardware
changes are not possible.
Note: The above work around is recommended
for users for whom application hardware
changes are possible, and also for users
whose application hardware already
includes a 32 kHz LP Oscillator crystal.
