Symmetrical pwm
WebThe N variable represents the prescaler divider (1, 8, 64, 256, or 1024).. The extreme values for the OCR 1 x Register represents special cases when generating a PWM waveform output in the phase correct PWM mode. If the OCR 1 x is set equal to BOTTOM the output will be continuously low and if set equal to TOP the output will be set to high for non-inverted …
