If a value less than 0x0010 is written to the DTRx and
ALTDTRx registers, either or both of the PWMHx and
PWMLx outputs will not function.
Duty cycle resolution is not 1.1 ns over the entire duty
cycle range.
The PWM Special Event Trigger and PWM Individual
Trigger do not function near the beginning of the PWM
period.
The dead-time registers (DTRx/ALTDTRx) must be
modified only when the PWM is not running and should
not be modified “on-the-fly”.
The PWM override feature does not work correctly.
Any duty cycle value less than or equal to 0x0010
causes the PWM outputs to flip to the inverted state.
The PWM fault, current-limit and output override
priorities do not work correctly.
In Push-Pull mode, with immediate updates enabled,
the PWM pins may become swapped.
The PWM module may not operate at temperatures
below -20ºC.
The PWM output may exhibit an occasional jitter
proportional to the operating speed of the
dsPIC30F1010/202X device.
Setting the XPRES bit in the PWMCONx register
should enable a current-limit source to reset the PWM
period when the PWM generated is configured in
Independent Time Base mode. This functionality is not
working correctly.
The Global Software Trigger bit (GSWTRG in the
ADCON register) is not reset unless the PxRDY bits in
the ADSTAT register are reset.
The resolution of the PWM to ADC sample-and-hold
trigger timing is up to 41.6 ns instead of the 8 ns
specified in the device data sheet.
Individual ADC Interrupts for the ADC pin pairs do not
work.
The maximum conversion rate for the ADC module is
1.5 Msps.
Depending on conversion configuration, ADC inputs that
do not have dedicated sample-and-hold circuits may
produce inaccurate conversion results.
