The three-phase motor control timer function is available by setting the INV02 bit in the INVC0 register to
"1". The timer B2 is used for carrier wave control and the timers A1, A2, A4 for three-phase PWM output
(U, U, V, V, W, W) control. An exclusive dead time timer controls dead time. Figure 16.8 shows an
example of the triangular modulation waveform. Figure 16.9 shows an example of the sawtooth modula-
tion waveform.

NOTES:
