    Hi Tanvi,

    1. Write 0x4C00 to register address 3E. This sets the data flash class to be accessed.

    2. read 1 byte at register address 0x58. This will return the product number.

    This uses the DataFlashClass() extended data command located at 3E. The product number is in the charger information subclass with subclass ID 76 (0x4C) and offset of 24 which means the data resides in the first data block (00). The address of the product number is 0x40 + offset which is 0x40 + 0x18.

    Best Regards,
    Ben Lough
