Hi all, 

does anyone know how to use the phase correct pwm.  I've tried still
not succeeded.

Dear, 
        The Phase correct PWM is use Timer cunter up and cunter down 
compare OCR0n to change output pulse.

You need to set timer counter register to try.

i've tried to set the register to enable the phase correct PWM ,then
input a value to ICR, but the pwm is the same as fast pwm.  I read the
datasheet but it is too advance to me.  Does anyone here can share
your experience on this topic?

Deal all,
" Phase correct PWM " and " Fast PWM " to me, " Phase correct
PWM " can accurate control pulse allow the location , if will not do
very accurate frequency to control I would build purpose and use "
Fast PWM ".

Even so " Fast PWM " can control the error in 0.5% - 1.5% with my
inferior level(Internal RC).
