    About the behavior of SYSTEM_STATUS register of MBR3




      I am trying to write user configurations to MBR3 in the following procedure:

      1. Read the SYSTEM_STATUS(0x8A) register

      2. If SYSTEM_STATUS (bit0) is 0, write configuration parameter to MBR3 (according to Register TRM)

      3. If it is 1, nothing is done.


      However, after doing this process, the SYSTEM_STAUTS register will be 0, but the configuration will remain at the factory default.

      I think that the SYSTEM_STATUS register is 1 at the time of shipment from the factory, and will be 0 when writing something.

      Is this correct?

      If not, please tell me when the SYSTEM_STATUS register will be 1.
