Module: Oscillator
6.1 HS Oscillator
The HS oscillator requires a minimum voltage of
3.0 volts (at 65°C or less) to operate at 20 MHz.
Work around
None.

Module: Enhanced Capture Compare
PWM (ECCP)
7.1 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
7.2 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:
The exact delay time will depend on the
TAD divisor (ADCS) selection. The TCY
counts shown in the timing diagram above
apply to this example only. Refer to
Table 3 for the required delay counts for
other configurations.
