In Debug mode (using the MPLAB
“Freeze on Halt” is selected (an option in the
MPLAB ICD 2 settings under the Program tab),
TMR5L will not increment properly when single
stepping if the prescaler is not set to 1:1.
Work around
None. Use in Debug mode only with the 1:1
prescaler.

A small number of parts may be difficult to program
successfully at certain voltages using the MPLAB
ICD 2.
Work around
If such a part is encountered, attempt to program
several times. If unsuccessful, adjust V
down slightly, within the operating range of the
device. If this is not possible, then try another part.
Date Codes that pertain to this issue:
All engineering and production devices.
When the PCPWM is operated in Complementary
mode with a non-zero dead-time value and the
duty cycle results in an active-low time of less than
1 T
for a new PWM period and the PWM output will
alternate between one PWM period high and one
PWM period low.
Work around
When in Complementary mode with a non-zero
dead-time value, ensure that the active-low time
will always be greater than 1 T
when dead-time is not equal to zero, ensure that:
