Timers’ functions for three-phase motor control
Figure 1.18.4. Timer mode registers in three-phase waveform mode
Three-phase motor driving waveform output mode (three-phase waveform mode)
Setting “1” in the mode select bit (bit 2 at 0348
mode that uses four timers A1, A2, A4, and B2 to be selected. As shown in Figure 1.18.4, 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.
