    Hi,
    I read this description of watchdog timer operation in Remote Update Intel® FPGA IP User Guide 2023.11.29, Table 2. Remote System Configuration Components in Intel Arria 10 and Intel Cyclone® 10 GX Devices. I think it's clear enough.

    The timer begins counting after the device goes into user mode. To ensure the application configuration is valid, you must continuously reset the watchdog reset_timer within a specific duration during user mode operation.


    If the application configuration does not reset the user watchdog timer before time expires, the dedicated circuitry reconfigures the device with the factory configuration and resets the user watchdog timer.

    Regards
    Frank

Great Thanks. Really I somehow have skipped it. Nevertheless It would be grateful to have the note about it between 6 and 7 steps of the section 1.3.1.1.1 as the same as it has done after 7 one as only it describing all necessary steps together.
