DEVICE EVALUATION SOFTWARE

After you complete the device and board selections, the evalua-

tion software loads, allowing full control over the selected

device. The software layout is the same for both the ADT7320

and ADT7420. There are three tabs in the evaluation software:

•

Configuration Register

•

Temperature Monitor

•

ADT7x20 Registers

The evaluation software also has Easy Setup and Close options.

Configuration Register

This tab allows you full control over the configuration register

of the selected device, as shown in Figure 7. At startup, the

evaluation software initializes the configuration register to the

default value of 0x90 (hexadecimal). For more details on how to

set the configuration register, consult the device data sheet.
