Figure 20.17
In this mode, 3 normal-phases and 3 counter-phases of the PWM waveform are output with the same period (three-
phase, sawtooth wave modulation, and no dead time).
Figure 20.17 shows a Block Diagram of Reset Synchronous PWM Mode, and Table 20.11 lists the Reset
Synchronous PWM Mode Specifications. Figure 20.18 shows an Operating Example of Reset Synchronous PWM
Mode.
Refer to Figure 20.16 Operating Example of PWM Mode (Duty 0%, Duty 100%) for an operating example of
PWM Mode with duty 0% and duty 100%.
Reset Synchronous PWM Mode
Note:
1.When bits BFC0, BFD0, BFC1, and BFD1 in the TRDMR register are set to 1 (buffer register).
