+ * *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 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.
