32. Touch Screen ADC Controller (ADC)

The StampA5D3x has a 12-bit Analog-to-Digital Converter, which includes a 4-wire or 5-wire resistive touchscreen controller. It integrates a 12-to-1 analog multiplexer, making analog-to-digital conversions of 12 analog lines possible. The conversions extend from 0V to the voltage carried on pin ADVREF and has configurable timings.
