    I just discovered that the STVD7 3.1.1. simulator does not update

    the WDGRF bit of the System Integrity Control/Status Register (SICSR)

    whenever a watchdog timeout resets the ST7FLITE29.

    According to the latest documentation (page 33 of ST7LITE2 datasheet

    Rev. 3.0 - October 2004) and my tests on shipping silicon,

    ''[the bit #4 of SICSR] is set by hardware

    (watchdog reset) and cleared by software

    (writing zero) or an LVD Reset (to ensure

    a stable cleared state of the WDGRF flag

    when CPU starts).''

    Regards,

    Thanks for reporting this bug.

    It is present on Lite watchdogs (Lite1, Lite2, Dali, Lite3, L3).

    Regards,
