Figure 17-4. PSCOUTnA & PSCOUTnB Basic Waveforms in One Ramp mode
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:
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.
