    Unlock interface with password via JTAG

    Hello all,

    I work for a company which produces its own universal in-system programmers. We are able to program the UCB_DBG area with a password (using our programmer) and then unlock it by using Miniwiggler tool. We need to support the unlocking mechanism for the interface with our programmer, but we can't find how to do so.
    How should the password be sent to the MCU in order to unlock the interface? Which are the steps we need to follow? We have access to full Aurix documentation, but we are not able to find a definitive answer.

    We are using JTAG as communication protocol and the current MCU we are using is a TC233LP-32F200F.

    Thank you in advance.
