11.7 PPG period limitation
PPG max period is determined by the PPGPXH/PPGPXL. After duty matching, period comparation is
enabled until period matching. If PPG counter value and PPGPXH/PPGPXL matches before PPG
counter value and PPGPH/PPGPL matches, the counter is cleared and waits for the start signal.
