[11:0] DATA[11:0]: ADC channel data
The ADC in STMPE610 operates on an internal RC clock with a typical frequency of
6.5 MHz. The total conversion time in ADC mode depends on the "SampleTime" setting,
and the clock division field 'Freq'.
The following table shows the conversion time based on 6.5 MHz, 3.25 MHz and 1.625 MHz
clock.
