In Push-Pull mode, with immediate updates
enabled, the PWM pins may become swapped.
Work around
If using the PWM module in Push-Pull mode,
immediate updates must be disabled.
Affected Silicon Revisions
The
temperatures below -20ºC. During this condition,
the PWM module will relinquish control of the
associated PWM pin and the Port I/O will
determine the state of the pin. In addition, the
PWM module will stop generating the ADC trigger
before the module relinquishes control of the PWM
pins.
Work around
None.
Affected Silicon Revisions
The outputs of the PWM module may exhibit a
jitter proportional to the speed of operation of the
device. The jitter may be observed as a deviation
in the PWM period, duty cycle or phase, and may
be affected independently of each other. As a
result, the maximum deviation exhibited on the
PWM output pin at 30 MIPS is 8.4 ns.
The jitter is caused by silicon process variations,
noise on the V
temperature of the dsPIC
given set of operating conditions, the maximum
jitter will be the same for all three parameters, and
independent of each other.

Speed of Operation
Table 3 shows the maximum jitter that may be
exhibited at various operating speeds.
The maximum jitter at any operating speed can
be determined using Equation 2.
Where:
• S is the speed of operation in MIPS.
The maximum percentage error observed on the
