AMC7832EVM User’s Guide
Either one of these windows can be programmed with the desired DAC output voltage or hexadecimal
value. When these values are entered, they are instantly written to the internal DAC buffer register.
Pressing the
Register Update button shifts the contents of the DAC buffer stage to the DAC latch stage,
which then updates the DAC output voltage.
The Read Back column allows the user to read back the register contents of either the latch or buffer
stage, which is selectable through the Boolean checkbox below the
Read DACs button, as shown in
Figure 17 . The results are read back after the Read DACs button is pressed.

5.2.5 AMC7832EVM ALARMS Page
The AMC7832 ALARMS page gives the user access to the programmable out-of-range alarms for the
internal temperature sensor and low-voltage ADC channels (ADC12 through ADC16).
Figure 18 displays
the ALARMS page of the AMC7832EVM. The page displays the name of each alarm, shown in the Alarm
Name column, and provides information such as the value, high limit, low limit, and alarm status, along
with other additional options.
Figure 18. ALARMS Page
To use the ALARMS page, enable the ADC channel or temperature sensor in the ADCs page of the GUI.
Achieve this by enabling the appropriate channel’s mux. After the channels are active, the Low Limit and
High Limit fields are available to edit (see
Figure 19 ).
