324 AI1 signal filter time 34567 (P1.2.8, P1.2.20, P1.2.2.2)
When this parameter is given a value greater than 0, the function that filters out
disturbances from the incoming analog signal is activated.
A long filtering time makes the regulation response slower. See Figure 8-20.
325 Analog input AI2 signal range 34567 (P1.2.10, P1.2.22, P1.2.3.3)
