Silicon Errata Summary
The following list summarizes the errata described in
this document:
this document:
1.
PWM Dead Time
If a value less than 0x0010 is written to the DTRx
and ALTDTRx registers, either or both of the
PWMxH and PWMxL outputs will not function.

2.
PWM Duty Cycle
Duty cycle resolution is not 1.1 ns over the entire
duty cycle range.

3.
PWM Triggers
The PWM Special Event Trigger and PWM
Individual Trigger do not function near the
beginning of the PWM period.

beginning of the PWM period.
4.
ADC Sample and Hold Timing
The resolution of the PWM to ADC sample and
hold trigger timing is 41.6 ns instead of the 8 ns
specified in the device data sheet.

6.
ADC Shared Sample and Hold Circuit
Depending on conversion configuration, ADC
inputs that do not have dedicated sample and hold
circuits may produce inaccurate conversion results.

ADC Global Software Trigger
The Global Software Trigger bit (GSWTRG in the
ADCON register) is not reset unless the PxRDY
bits in the ADSTAT register are reset.

8.
RB7 Pin and All Multiplexed Functions
The RB7 pin does not work. This pertains to all
multiplexed functions on RB7 as well.

9.
ADC Conversion Rate
The maximum conversion rate for the ADC module
is 1.5 Msps.

10. Current Reset Mode
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.
