phase waveform. In this way, a waveform can be picked up from the applicable terminal in a manner in
which the "L" level of the U phase waveform doesn’t lap over that of the U phase waveform, which has the
opposite phase of the U phase waveform. The width of the “L” level too can be adjusted by varying the
values of timer B2, timer A4, and timer A4-1. In dealing with the V and W phases, and V and W phases,
the latter are of opposite phase of the former, have the corresponding timers work similarly to dealing with
the U and U phases to generate an intended waveform.
