The Conter Start Bit STR of Timer Start Register H8/300H in PWM of 0 in ITU

Latest Updated:03/26/2009

Question:

When setting the PWM output for H8/3802 and H8/38024 series, how does the output waveform vary when the setting value of PWM data register is not a multiple of 4 ?

Answer:

When the value of PWDR/4 is 1 over a multiple of 4, constituent of tf/2 is added to tH2. When the value of PWDR/4 is 2 over a multiple of 4, constituent of tf/2 is added to each tH2 and tH4 respectively. When the value of PWDR/4 is 3 over a multiple of 4, constituent of tf/2 is added to each tH2 tH3 and tH4 respectively.
