-+ *    *Note: A value of X for address is a don't care condition.
-+ *    **Note: There are 8 address bits for the 93C56/66 chips unlike
-+ *	      the 93C46/26/06 chips which have 6 address bits.
-+ *
-+ *   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.
