Hi all ! It's correct to say : 1) if CCPR1L+CCP1X+CCP1Y > PR2*4 the Duty cycle of the PWM signal will = be 100% ?????? 2) if CCPR1L+CCP1X+CCP1Y =3D 0 the Duty cycle will be 0% ????? DS31014A is not very clear: If TMR2 is a 8 bit timer acting as 10 bit counter with the 2 LSB = comming from the Q cycle or prescaler and the PR2 is an 8 bit reg. Can I say in that case (PWM mode 10 bit reg), the PR2 will compare only = with the 8 MSB of the 10 bit counter what will be the same as a = comparison between CCPR1L+CCP1X+CCP1Y and PR2*4 ???????? ..... errrh, I hope someone could understand ... :-) TIA, Fabio Pereira -- http://www.piclist.com#nomail Going offline?
