Method 4: Use the software-enabled BOR
as described in Method 3, but use
the following sequence:
a) Switch to internal 32 kHz oscil-
lator immediately before Sleep;
b) Upon wake-up, turn on FVR
(FVREN bit of the FVRCON
register);
c) Manually turn on the BOR;
d) Switch the clock back to the
preferred clock source.

PWM (ECCP)
4.1 Enhanced PWM
When the PWM is configured for Full-Bridge mode
and the duty cycle is set to 0%, writing the
PxM<1:0> bits to change the direction has no
effect on PxA and PxC outputs.
Work around
Increase the duty cycle to a value greater than 0%
before changing directions.
Affected Silicon Revisions
4.2 Enhanced PWM
In PWM mode, when the duty cycle is set to 0%
and the STRxSYNC bit is set, writing the STRxA,
STRxB, STRxC and the STRxD bits to enable/
disable steering to port pins has no effect on the
outputs.
Work around
Increase the duty cycle to a value greater than 0%
before enabling/disabling steering to port pins.
Affected Silicon Revisions
Note: When using the software BOR, follow the
steps in Methods 3 or 4 above when
enabling BOR for the first time during
program execution.
