Important:
It is recommended to edit these field with
in ATE mode or via VCC externally powered.
If the parameters are written whilst STNRG011 is running, they will be overwritten when STNRG011 is shut down.
When STNRG011 is powered up, it makes a copy of the event history in its RAM, which changes during the active phase. At
shutdown, the RAM content will be overwritten in the E²P, hence the E²P content will be overwritten.

Additional tools
The GUI embeds some additional tools useful during the power supply integration phase.
10.4.1
PSU monitor
Note:
A specific patch is needed to access this feature. Contact STMicroelectronics sale office for details.
The PSU monitor provides similar information to the power metering, but only on a specific request by the GUI
(different from the power metering information sent continuously by
).
In this case, the GUI reads the STNRG011 memory directly and additional information can be retrieved.
