There are three modes in APIS:
APIS mode 1: reports the strongest output only (Figure 3).
APIS mode 2: reports all outputs that exceeds pre-defined thresholds (value of Strength Threshold register) (Figure 4).
APIS mode 3: reports two strongest outputs (suitable for multi-touch applications) (Figure 5).
All three modes are described in the Figures below. The red-colored circles and bars show the output.
