V errate (vypis na konci mailu) pro 18F8722 se pise, ze nejde nulovani TMR1 
a TMR3 pres moduly CCP. Pisou tam vsechny revize, ale mi to jde. Presneji 
TMR1 se nuluje ale TMR3 ne.
Co s tim? Mam nulovat softwarove i TMR1?

3. Module: Timer1/Timer3
When Timer1 or Timer3 is the time base for CCPx,
and the associated CCPxCON register is configured
with 0x0B (Compare mode, trigger special
event), the assigned timer is not reset on a Special
Event Trigger.
Work around
Modify firmware to reset the Timer registers
(TMRxL and TMRxH) upon detection of the
compare match condition.
Date Codes that pertain to this issue:
All engineering and production devices.
