Si3452MS8-KIT
Rev. 0.6

The Si3452 Monitor supports several different USB-to-I
2
C devices. If more than one of these devices is connected
to the PC at the same time, then the user can select which one to use with the Interface drop-down box.
The “Dummy” device is a substitute device that does not actually perform I
2
C communications. The Dummy device
allows the Si3452 Monitor to open even if there are no USB-to-I
2
C devices connected to the PC.
The version of the Si3452 Monitor is displayed at the bottom of the window.
5.1.3. Device Information
The Device Information box displays high level information about the Si3452 device.
Figure 11. Device Information Box
This box displays the hardware revision of the silicon, the firmware version, and the measured Vee voltage. The
user can update the Vee voltage by clicking on the “Vee” button.
5.1.4. Device Status
The Device Status box displays the high level status of the Si3452 device.
Figure 12. Device Status Box
This box displays the contents of the Device Status register. If the temperature of the Si3452 controller is too high,
then the “Over temp” LED bar is bright red instead of dark red. If the Vee voltage is too low, then the “Vee UVLO”
LED bar is bright red instead of dark red. This box also displays the setting of the detection back-off timing
(Alternative A or Alternative B).
The user may manually update this box by clicking on the “R” (read) button. The GUI reads the Device Status
register and updates the status information displayed in this box. This box is not updated by polling or by the
“Refresh” button unless the CoR check box is checked.
If a device event bit is set in the interrupt register, then the “R” button is red. This indicates that the displayed device
status is stale and that the Device Status register should be read. Reading the Device Status register has the side
effect of clearing the device event bits in the interrupt register, consequently making the “R” button no longer red.
The “Toggle detection back-off timing” button switches the detection back-off timing between Alternative A and
Alternative B. This change may not automatically be displayed in this box. The user may have to click on the “R”
button to see the new timing setting. If the Device Status register has never been read, then this box displays
“Alternative?” because the timing is not known.
