Figure 12.3.9. Triangular Wave Modulation Operation

The three-phase motor control timer function is enabled by setting the INV02 bit in the VC0 register to “1”.
When this function is on, timer B2 is used to control the carrier wave, and timers A4, A1 and A2 are used to
control three-phase PWM outputs (U, U, V, V, W and W). The dead time is controlled by a dedicated dead-
time timer. Figure 12.3.9 shows the example of triangular modulation waveform, and Figure 12.3.10 shows
the example of sawtooth modulation waveform.
