CHAPTER 9 TIMER/COUNTER FUNCTION (REAL-TIME PULSE UNIT)
(c) When BFCMnx = 0000H is set
Figure 9-35. Operation Timing in PWM Mode 2 (Sawtooth Wave, BFCMnx = 0000H)
count value
BFCMnx
CM0nx
Interrupt request
DTMnx
Positive phase
(TO0n0, TO0n2, TO0n4)
Negative phase
(TO0n1, TO0n3, TO0n5)
Note Set by rising edge of TM0CEn bit
Remarks 1. n = 0, 1
2. x = 0 to 2
3. t: Dead time = (DTRRn + 1)/f
4. The above figure shows an active high case.
5. W: Width between CM0n3 match and CM0nx match (timer count clock)
If CM0nx = 0000H has been set, the output waveform resulting from the TM0n count clock rate and the
DTRRn set value differ.
