ATmega16M1/32M1/64M1
Center Aligned Mode
In center aligned mode, the center of PSCOUTnA and PSCOUTnB signals are centered.
Figure 17-6. PSCOUTnA & PSCOUTnB Basic Waveforms in Center Aligned Mode
On-Time 0 = 2 × POCRnSAH/L × 1/Fclkpsc
On-Time 1 = 2 × (POCRnRBH/L - POCRnSBH/L + 1) × 1/Fclkpsc
Dead-Time = (POCRnSBH/L - POCRnSAH/L) × 1/Fclkpsc
PSC Cycle = 2 × (POCRnRBH/L + 1) × 1/Fclkpsc
Note:
Note that in center aligned mode, POCRnRAH/L is not required (as it is in one-ramp mode) to
control PSC Output waveform timing. This allows POCRnRAH/L to be freely used to adjust ADC
synchronization.
