ADC Control Section
This section controls all the parameters of the A/D converter. Each slider
controls one parameter, whose value is shown next to the slider. Each slider
is described below.

-
Resolution
Selects between 8-, 10-, and 12-bit resolution.
-
Conversion Clock
The internal clock which runs the A/D converter can run at 8, 4, 2, or 1 MHz.
When running at 8 MHz, only 8-bit resolution is possible; when running at
4 MHz, 8- or 10-bit resolution is possible, but 12-bit is not. These restric-
tions are reflected in the operation of this program, since only 1 or 2 MHz
clock rates allow 12-bit resolution to be chosen.

Panel Voltage Stabilization Time
This is the time that the TSC2301 allows for the touch screen to settle after
turning the drivers on.

Precharge Time
-
Sense Time
These two parameters are the time allowed to precharge the touch panel
capacitance and then sense to see if the screen is touched. For more de-
tails on these parameters, refer to the TSC2301 data sheet.
