8.3.5 Reset Synchronous PWM Mode
In this mode, three normal-phases and three counter-phases of the PWM waveform are output with the same period
(three-phase, sawtooth wave modulation, and no dead time).
Figure 8-55 shows the Block Diagram of Reset Synchronous PWM Mode, Table 8-17 lists the Reset Synchronous PWM
Mode Specifications, Figure 8-56 shows an Operation Example in Reset Synchronous PWM Mode.
See Figure 8-54 Operation Example in PWM Function (Duty Cycle 0%, Duty Cycle 100%) for an operation example
in PWM Mode with duty cycle 0% and duty cycle 100%.
