Haptics Enabled 4/5-Wire
Resistive Touchscreen Controller with Proximity Sensing
touchscreen is used as the proximity sensor and is being touched when the conversion is performed, the
proximity measurement result may be incorrect.
Figure 41 – Manual Mode – CONVERT Command (CHAN = Y ; PROXSCANPERIOD != 0; Pen down)
If the screen is not touched, only the proximity sensing operation is performed.
Figure 42 – Manual Mode – CONVERT Command (CHAN = Y ; PROXSCANPERIOD != 0, Pen up)
In PENDET and PENTRG mode, a proximity sensing operation will be performed regularly as defined in
PROXSCANPERIOD, but only if pen is not detected.
