1 Introduction

This user manual describes the operation of

the IQS253EV02 Evaluation Kit. The EV-Kit is

manufactured in three parts, consisting of a

mainboard, and two separate plug-in module

boards. To adjust IC OTP settings, the main

board can be interfaced to any personal

computer with the Azoteq Configuration Tool

(CT220), and making the adjustments by

means of theUSBProg software. The purpose
