Reset Synchronous PWM Mode

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 16.112 shows a Block Diagram of Reset Synchronous PWM Mode, and Table 16.43 lists the Reset

Synchronous PWM Mode Specifications. Figures 16.113 to 16.120 show the Registers Associated with Reset

Synchronous PWM Mode and Figure 16.121 shows an Operating Example of Reset Synchronous PWM Mode.

Refer to Figure 16.111 Operating Example of PWM Mode (Duty 0%, Duty 100%) for an operating example

of PWM Mode with duty 0% and duty 100%.
