The 10-bit or 12-bit CMOS analog to digital converter (ADC) comprises of 10-channel analog inputs. It convertsThe analog input signal into 10-bit or 12-bit binary digital codes at a maximum conversion rate of 1 MSPs5 MHz A/D converter clock. A/D converter operates with On-Chip sample-and-hold function. ADC supports lowPower mode.Touch screen interface can control input pads (XP, XM, YP, and ym) to obtain x/y-position on the external touchScreen device
