4.7 Programmer Powers the Target System

4.7.1 Overview

The PPM3 programmer is capable of supplying a controlled voltage from 3.0 to 5.0V to power the
Target System at a maximum current of 300mA. This allows the programmer to power the Target
System via the ISP Cable and switch power on / off under Programming Project / Script control. The
voltage and current settings must be set up in the Programming Project prior to powering up the
Target System. In this mode it is also possible for the programmer to automatically sense whether a
Target System is connected to the programmer – see Target Sensing section.
