Positive phase
(TO0n0, TO0n2, TO0n4)
Negative phase
(TO0n1, TO0n3, TO0n5)
Remarks 1. n = 0, 1
2. x = 0 to 2
3. b = CM0n3
4. t: Dead time = (DTRRn + 1)/f
5. The above figure shows an active high case.
If match signal INTCM0n3 for TM0n and CM0n3 and the match signal for TM0n and CM0nx conflict,
reset of the F/F takes precedence, so that the F/F does not get set following match of CM0nx (= CM0n3)
with TM0n.
