TSC2301
SLAS371D–SEPTEMBER 2002–REVISED AUGUST 2004
host recognizes the interrupt request. Instead of starting a sequence in the TSC2301, 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 TSC2301 to turn on X-drivers. (c) Host waits a
desired delay for panel voltage stabilization. (d) Host writes to TSC2301 to begin X-conversion. After waiting for
the settling time, the host then addresses the TSC2301 again, this time requesting an X coordinate conversion.
The process is then repeated for Y and Z coordinates. The processes are outlined in
Figure 58
through
Figure 60
.
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:
