Figure 16-9. PSCn0 & PSCn1 Basic Waveforms in Center Aligned Mode
On-Time 0 = 2 * OCRnSAH/L * 1/Fclkpsc
On-Time 1 = 2 * (OCRnRBH/L - OCRnSBH/L + 1) * 1/Fclkpsc
Dead-Time = (OCRnSBH/L - OCRnSAH/L) * 1/Fclkpsc
PSC Cycle = 2 * (OCRnRBH/L + 1) * 1/Fclkpsc
Note:
OCRnRAH/L is not used to control PSC Output waveform timing. Nevertheless, it can be useful
to adjust ADC synchronization (
