    Hello Sonoki-san,

    Clicking on the "Balance ON" button sends a write to the CBENBL register (address 0x14) with the value configured in the upper left of the GUI (in your case, 0x3814), followed by a read of the CBENBL register for the GUI to verify the write occurred.

    Clicking on the "Balance OFF" button sends a write to the CBENBL register (address 0x14) with the value of 0x0000.

    Regards,

    Stephen
