Dead-Time 1
PSCOUTn0 and PSCOUTn1 signals are defined by On-Time 0, Dead-Time 0, On-Time 1 and
Dead-Time 1 values with :
On-Time 0 = (OCRnRAH/L - OCRnSAH/L) * 1/Fclkpsc
On-Time 1 = (OCRnRBH/L - OCRnSBH/L) * 1/Fclkpsc
Dead-Time 0 = (OCRnSAH/L + 1) * 1/Fclkpsc
Dead-Time 1 = (OCRnSBH/L + 1) * 1/Fclkpsc
Note: Minimal value for Dead-Time 0 and Dead-Time 1 = 1/Fclkpsc
16.5.2.3
One Ramp Mode
In One Ramp mode, PSCOUTn0 and PSCOUTn1 outputs can overlap each other.
