SLAS372 — NOVEMBER 2002
Figure 57. Z Coordinate Reading Initiated by Host.
Conversion Controlled by the Host
In this mode, the TSC2300 detects when the touch panel is touched and causes the PENIRQ line to go low. The host
recognizes the interrupt request. Instead of starting a sequence in the TSC2300 which then reads each coordinate in
turn, the host now must control all aspects of the conversion. An example sequence would be: (a) PENIRQ goes low
when screen is touched. (b) Host writes to TSC2300 to turn on X-drivers. (c) Host waits a desired delay for panel
voltage stabilization. (d) Host writes to TSC2300 to begin X-conversion. After waiting for the settling time, the host then
addresses the TSC2300 again, this time requesting an X coordinate conversion.
