Figure 10-8 and Figure 10-9 give examples of T3’s operation, visualizing count signal

generation and direction control. It also shows how input jitter is compensated which

might occur if the sensor rests near to one of its switching points.

Evaluation of the Incremental Encoder Signals

Note: Timer T3 operating in incremental interface mode automatically provides

information on the sensor’s current position. Dynamic information (speed,

acceleration, deceleration) may be obtained by measuring the incoming signal

periods. This is facilitated by an additional special capture mode for timer T5.

Note: This example shows the timer behaviour assuming that T3 counts upon any

transition on input, i.e. T3I = '011
