eFUSE Overview

eFUSE tool provides an intuitive graphical interface for writing/programming the OTP (One Time Programable) bits by software. All eFUSE bits have by default the value 0 and can only be blown from 0 to 1 once, without the possibility of reverting the value.

The main flow of using the tool consists in configuring the eFUSE values in the UI based on the desired scenario and generating a binary image which needs to be downloaded on the target to apply the selected values on the hardware.
