Select the platform.2. Click OK. A label identifying the platform is included at the top of the schematic diagram.5.4.1 Managing devicesThe following buttons enable you to manage the devices in your configuration:• Click Add... to add a device to the scan chain.• When a device is selected in the schematic diagram:— click Remove to remove the selected device— click Properties... to update the properties for the selected device— click Configure to display the Device configuration settings• For a scan chain containing multiple devices, click:— Move Left to move the selected device to the left— Move Right to move the selected device to the right.ARM DUI 0498F Copyright © 2010-2012 ARM.
