DAC80502 Evaluation Module

3.2.2

Software Features

The DAC80502 EVM incorporates interactive functions that help configure the DAC80502 device. These
functions are built into several GUI pages, as shown in

Figure 7

The

Page Selection

menu allows the

user to switch between the pages, with each page representing a feature of the software.

3.2.2.1

Low Level Configuration Page

The DAC80502 EVM

Register Map

page, shown in

Figure 8

, allows the user to access low level

communication directly with the DAC80502 registers. Selecting a register on the

Register Map

list shows a

description of the values in that register, as well as information on the register address, default value, size,
and current value. Values can be read and written to the registers by writing to the

Value

or bit field of the

GUI.
