10.6.18 Example for Using the TOM in Motor Control Applications
The microcomputer contains two blocks of TOM timers which are designed to reduce software load
during motor control. This section explains an example for using TOM0 in motor control
applications.
The three-phase motor control waveforms start TOM0 according to the TOM0 startup timing at a
fixed period of 20 kHz generated by TID0. By using the TOM0's internal single-shot PWM function,
the output waveform can easily be configured because the waveform data only needs to be stored
at the necessary rewrite timing. The H and L transistor short-circuiting prevention time can be
accomplished by changing the TOM0 setup time in software. Up to 8-phase motors can be
controlled by a combined use of TID and TOM.
