Figure 1.14.6. Timer mode registers in three-phase PWM output mode

Three-phase motor driving waveform output mode (three-phase PWM output mode)

Setting “1” in the mode select bit (bit 2 at 034816) shown in Figure 1.14.1 - causes three-phase PWM

output mode that uses four timers A1, A2, A4, and B2 to be selected. As shown in Figure 1.14.6, set

timers A1, A2, and A4 in one-shot timer mode, set the trigger in timer B2, and set timer B2 in timer mode

using the respective timer mode registers.
