Y co-ordinate measurements are similar to Y co-ordinate measurements. However, the voltage
gradient on the bottom plate is in the Y direction instead of the X direction. This is achieved by
grounding the bottom left and bottom right corners of the touchpanel, and connecting the top left and
top right contacts to TPVDD.
Figure 31 Pen Down Detection on 5-wire Touchpanel
Pen down detection works in a similar fashion for both 4-wire and 5-wire touchpanels (see Four-Wire
Touchpanel Operation). On a 5-wire touchpanel, all four contacts of the bottom plate are grounded,
and the top plate contact is connected to the internal programmable pull-up resistor, R
