ADC & TOUCH SCREEN INTERFACE
This chapter describes the functions and usage of ADC and Touch Screen interface.
7.1 OVERVIEW OF ADC & TOUCH SCREEN INTERFACE
The 10-bit or 12-bit CMOS Analog to Digital Converter (ADC) comprises of 10-channel analog inputs. It converts
the analog input signal into 10-bit or 12-bit binary digital codes at a maximum conversion rate of 1MSPS with
5MHz A/D converter clock. A/D converter operates with on-chip sample-and-hold function. ADC supports low
power mode.
Touch Screen Interface can control input pads (XP, XM, YP, and YM) to obtain X/Y-position on the external touch
screen device. Touch Screen Interface contains three main blocks, namely, touch screen pads control logic, ADC
interface logic and interrupt generation logic. There are two set of touch screen interfaces, which share one ADC.
