RTFM!

Page 23 DS30292A
"TMR2IF: TMR2 to PR2 match interrupt flag
1=TMR2 to PR2 register capture occurred (must be cleared in software)"

Since one sets the PWM period by writing to the PR2 register, and
since TMR2 gets cleared when it is equal to PR2, it -should- generate
and interrupt at the end of every cycle. You'll have to clear the flag
in software.

See page 59 for details of PWM regesters bits. TMR2IF * TMR2IE are
listed
as associated with PWM so clearly an interrupt is possible.

One should not be trying to program this device if one does not have
the full data sheet. There are just too many ways to screw up. In other
words, do you -own- homework.
