AMC7832EVM User’s Guide
The ALARMIN-ALR-OUT checkbox enables the propagation of alarm signals by allowing the user to input
an active-low signal to the ALARMIN pin, which then creates an active low signal on the ALARMOUT pin.
These functions need to be set in the GPIO configuration register, which is available for configuration in
the GPIO page of the AMC7832EVM GUI.
5.2.6 AMC7832EVM GPIO Page
The AMC7832 GPIO page features the first four (GPIO0 to GPIO3) general-purpose I/O of the AMC7832
device. These four GPIOs are also configurable for other specific functions, including the ability to
externally trigger conversions, enable alarms, and provide an output indicating conversion completion. The
GPIO page also provides a detailed description textbox that gives more information about the different
GPIO pins as the user hovers over the pulldown list under the GPIO Block column (see
Figure 22 ).
Figure 22. GPIO Page
Use the GPIO Block section of the GPIO tab, as shown in Figure 23 , to set the various GPIO functions.
The drop-down menu defaults to general-purpose I/O. To perform a write or read, set the W/R Function
pulldown to either Write or Read. The W/R value enables the user to input or observe the Boolean value
of the GPIO register. Press the
Generate Write/Read button to write to or read from the GPIO pin.
