4.1.4 Step 4: Configure Alert

The Alert pin allows the user to set limits on the value of the output register corresponding to the parameter selected from the drop-down menu, as shown in Figure 4-5. If at any time the register value violates the user-specified limit, a flag is triggered on the Alert pin. Note that the Alert pin is set to active low by default. Users can specify the limit value in the Alert Limit box.

In addition to the INA260EVM software alert configuration, the Alert Configuration box includes the Conversion Ready button that allows for a special functionality on the Alert pin. When the INA260 completes the conversions for the current operation, the conversion triggers the Alert pin and notifies the user that another conversion can be performed. In most cases, the INA260 conversion ready flag is not visible because of the speed of the INA260 conversion process.
