Conversion Controlled by TSC2301 Initiated By Host Responding to PENIRQ
TSC2301
SLAS371D – SEPTEMBER 2002 – REVISED AUGUST 2004
This mode is provided for users who want more control over the A/D conversion process. This mode requires
more overhead from the host processor, so it is generally not recommended.
In this mode, the TSC2301 detects when the touch panel is touched and causes the PENIRQ line to go low. The
host recognizes the interrupt request, and then writes to the ADC control register to select one of the touch
screen scan functions (single X-, Y-, or Z-conversions, continuous X/Y or X/Y/Z1/Z2 Conversions). The
conversion process then proceeds as described above, and as outlined in Figure 53 through Figure 57.
The main difference between this mode and the previous mode is that the host, not the TSC2301, decides when
the touch screen scan begins after responding to a PENIRQ. In this mode, the host must either monitor both
PENIRQ and DAV, or wait a minimum time after writing to the A/D converter control register. This wait time can
be calculated from Equation 6 in the case of single conversions, or from Equation 4 or Equation 5 in the case of
multiple conversions. The nominal conversion times calculated by these equations should be extended by
approximately 12% to account for variation in the internal oscillator frequency.
