About access to G2iM+ private User memory

I’m configuring the memory layout of a UCODE G2iM+ RFID tag using the memConfig word to allocate space for both EPC and User memory. I’ve set the memConfig value to 0343h, which according to the tag’s documentation should reserve the User Password block at addresses 1C0h to 1DFh. However, every time I attempt to write to that range, I receive a “03” (memory overrun) error. I suspect I’ve misunderstood some part of the configuration process. If anyone has successfully programmed the User Password section on this tag, I’d greatly appreciate your guidance.

I think you are not writing to a right address.

Please check the memory map in datasheet.
