I'm new in this forum and also a newbie concerning the handling of a microcontoller.
So in advance, please excuse my diction.
I'm using a MC9S12C128 and I'm trying to change the dutycycle of the PWM signal every period, in order to generate a sine like waveform (of the voltage amplitude) on the output pin.
My problem is that I don't know when to write to the PWMDTYx register and how to get the information when a period is over and the PWMDTYx is buffered to be able to write the next information to the PWMDTYx for the following period.
Thanks for your help.
