Output 3 normal-phases and 3 counter-phases of the PWM waveform with the same period (no three-phase,
sawtooth wave modulation and dead time).
Figure 14.76 shows the Block Diagram of Reset Synchronous PWM Mode, Table 14.29 lists the Reset
Synchronous PWM Mode Specifications. Figures 14.77 to 14.84 show the Registers Associated with Reset
Synchronous PWM Mode and Figure 14.85 shows the Operating Example of Reset Synchronous PWM Mode.
Refer to Figure 14.75 Operating Example of PWM Mode (Duty 0%, Duty 100%) for the operation example
in PWM Mode of duty 0% and duty 100%.
Reset Synchronous PWM Mode
NOTE:
1. When the BFC0, BFD0, BFC1 and BFD1 bits in the TRDMR register are set to 1 (buffer register).
