CHAPTER 9 TIMER/COUNTER FUNCTION (REAL-TIME PULSE UNIT)
Figure 9-15. Operation Timing in PWM Mode 0 (Symmetric Triangular Wave)
TM0n count value
Interrupt request
Positive phase
(TO0n0, TO0n2, TO0n4)
Negative phase
(TO0n1, TO0n3, TO0n5)
Remarks 1. The above figure shows the timing chart when BFTE3 and BFTEN of the TMC0n register are 1,
and transfer from BFCMn3 to CM0n3, or from BFCMnx to CM0nx is enabled. Transfer is not
performed when BFTE3 = 0 or BFTEN = 0.
2. n = 0, 1
3. x = 0 to 2
4. t: Dead time = (DTRRn + 1)/f
5. To not use dead time, set the TM0CEDn bit of the TMC0n register to 1.
6. The above figure shows an active high case.
Figure 9-16 shows the overall operation image.
