++ *
++ *   The 93Cx6 has a four wire interface: clock, chip select, data in, and
++ *   data out.While the ADM6996 uning three interface: clock, chip select,and data line.
++ *   The input and output are the same pin. ADM6996 can only recognize the write cmd.
++ *   In order to perform above functions, you need
++ *   1. to enable the chip select .
++ *   2. send one clock of dummy clock
++ *   3. send start bit and opcode
++ *   4. send 8 bits address and 16 bits data
++ *   5. to disable the chip select.
