Figure 9-32. Operation Timing in PWM Mode 2 (Sawtooth Wave, BFCMnx > CM0n3) (1/2)
(a) Operation timing of compare registers 0n0 to 0n2 (CM0n0 to CM0n2)
count value
Interrupt request
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.
6. INTCM01x is generated on a match between TM01 and CM01x (a in the above figure).
INTCM00x is not generated.
