2.1.3 Output Interrupt Signaling
The EOC pin can be configured to two different purposes, either as End-Of-Conversion signaling or as Interrupt output. Both options require
the ZSSC324x device to use corrected data. If the device is set to provide only raw data, the EOC pin is not functional. Information on how
to set the device to work with corrected data is presented in section 2.3.1 .
With the EOC configuration INT_setup = 00
the Apply Settings and Close button converts the inputs in the proper format (the values must be input in the decimal representation).
Figure 15 displays the selectable lower and upper threshold values for the interrupt configuration (see ZSSC324x Data Sheet for details
on thresholds).
Modifications entered in the dialog are valid for further communication after this window is closed. To save the changes in the ZSSC324x's
memory, adjust the parameters as needed and click the Copy Settings to Memory button to transfer it to the NVM tab on the GUI. As a
result, the register 02
(Interface Configuration) and/or registers 18

changed. Click the Write NVM button at the bottom of the GUI to write the new content into the memory.

2.2 Current Interface Settings
When the I2C communication interface is selected (see Figure 13), the Scan I2C bus button is enabled on the main screen. It provides the
ability to scan the I2C bus to determine the I2C address of the ZSSC324x. Selecting Scan I2C address triggers the scan during which the
ZSSC324x status is requested for each address ranging from 00
by the ZSSC324x, the scan stops, and this address is used for further communication during the current GUI session. The result of the
scan is indicated on the Information Bar:
