7.2.3 Analog Signal Processing
Fig. 7-6 Analog signal processing
Electrical control on internal variables is available only after ADC conversion and offset of external analog
signals, and judgment of dead zone signals.
For offset processing, see the left part in Fig. 7-6; for dead zone processing, see the right part in Fig. 7-6.
