16. Three-Phase Motor Control Timer Function
The PWM waveform can be output by using timers B2, A1, A2, and A4. Timer B2 is used for the carrier wave control,
and timers A4, A1, and A2 for the U-, V-, and W-phase PWM control.
Table 16.1 lists specifications of the three-phase motor control timer functions. Table 16.2 lists pin settings. Figure
16.1 shows a block diagram. Figures 16.2 to 16.10 show registers associated with the three-phase motor control timer
function.
