THREE-PHASE WAVEFORM MODE
10.4 Three-phase mode 1
10.4 Three-phase mode 1
10.4.1 Setting for three-phase mode 1
In the triangular wave modulation, three-phase mode 1 is more efficiently controllable than three-phase
mode 0. Therefore, three-phase mode 1 can mitigates the software’s load.
Figure 10.4.1 and Figure 10.4.2 show an initial setting example of registers relevant to three-phase mode
1, and Figure 10.4.3 shows a data-updating example in three-phase mode 1.
Note that the initial output level at the three-phase waveform output pin is undefined. Be sure to start the
three-phase waveform output (in other words, the waveform output is enabled.) after the output level at the
three-phase waveform output pin is stabilized.
