TSC2302
SLAS394–JULY 2003
Conversion Controlled by the Host
In this mode, the TSC2302 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 TSC2302, 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 TSC2302 to turn on X-drivers. (c) Host waits a
desired delay for panel voltage stabilization. (d) Host writes to TSC2302 to begin X-conversion. After waiting for
the settling time, the host then addresses the TSC2302 again, this time requesting an X coordinate conversion.
The process is then repeated for Y and Z coordinates. The processes are outlined in Figure 53 through Figure
55.
The time needed to convert any single coordinate under host control (not including the time needed to send the
command over the SPI bus) is given by:
