? So what is the real problem then? If you can set TMRx, OCx R/RS 
as you say i dont see why these wouldn't be used to avoid the glitch?

How do we know that the OC registers emideately update timer count?
We dont because they dont, becuse they are in toggle mode, OC registers are usually used in PWM generation. Where in the timer manual does it 
say timer count gets updated on a new reload of TMRx register?
I cant find it!?

Whats the difference between PRx and TMRx in comparator toggle mode?
