Using timer one for pwm.
Durring my research of the timer1 and timer 0 functions, I have come to 
the conclusion that if using 3 match registers for generating the pwm 
outputs, and then using the third match reg for the cycle length to 
reset the pwm. Am I correct in setting up the MCR register to allow the 
third match register to clear the timer counter?

Or is their a hardware function not documented that does the 
housekeeping automatically and resets the timer counter when any match 
register is used as the cycle length counter.

The only reason I bring this up is to the following:

The doc says page 196 15.5.12 sec para "the timer is reset by the match 
reg that is configured to set the pwm cycle length".

Any help on this issue would be great!
