Output 3 normal-phases and 3 counter-phases of the PWM waveform with the same period (with three-phase,
triangular wave modulation and dead time).
Figure 14.86 shows the Block Diagram of Complementary PWM Mode, Table 14.31 lists the Complementary
PWM Mode Specifications. Figures 14.87 to 14.95 show the Registers Associated with Complementary PWM
Mode, Figure 14.96 shows the Output Model of Complementary PWM Mode and Figure 14.97 shows the
Operating Example of Complementary PWM Mode.
