On-Time A = (POCRnRAH/L - POCRnSAH/L) × 1/Fclkpsc
On-Time B = (POCRnRBH/L - POCRnSBH/L) × 1/Fclkpsc
Dead-Time A = (POCRnSAH/L + 1) × 1/Fclkpsc
Dead-Time B = (POCRnSBH/L - POCRnRAH/L) × 1/Fclkpsc
Note: Minimal value for Dead-time A = 1/Fclkpsc.
If the overlap protection is disabled, in One-Ramp mode, PSCOUTnA and PSCOUTnB outputs can be
configured to overlap each other, though in normal use this is not desirable.

18.5.3.2. Center Aligned mode
In center aligned mode, the center of PSCOUTnA and PSCOUTnB signals are centered.
