In this mode, 3 normal-phases and 3 counter-phases of the PWM waveform are output with the same period
(three-phase, triangular wave modulation, and with dead time).
Figure 14.85 shows a Block Diagram of Complementary PWM Mode, and Table 14.31 lists the
Complementary PWM Mode Specifications. Figures 14.86 to 14.94 show the Registers Associated with
Complementary PWM Mode, Figure 14.95 shows the Output Model of Complementary PWM Mode, and
Figure 14.96 shows an Operating Example of Complementary PWM Mode.
