3 Low Level Page

The following section describes features of the Low Level Page in DS320PR410 GUI. This page can be used to access individual registers of each DS320PR410 device, change specific device settings, verify current device status, and to verify changes from the GUI High Level Page. For further information on DS320PR410 registers, please refer to the DS320PR410 Programming Guide.

1. Use the Device Select drop-down menu shown in Figure 3-1 to select which device is desired to read or write to. The DS320PR410-RSC-EVM includes four downstream and four upstream devices.
