++/* NOTES
++ * The instruction set of the 93C66/56/46/26/06 chips are as follows:
++ *
++ * Start OP *
++ * Function Bit Code Address** Data Description
++ * -------------------------------------------------------------------
++ * READ 1 10 A7 - A0 Reads data stored in memory,
++ * starting at specified address
++ * EWEN 1 00 11XXXXXX Write enable must precede
++ * all programming modes
++ * ERASE 1 11 A7 - A0 Erase register A7A6A5A4A3A2A1A0
++ * WRITE 1 01 A7 - A0 D15 - D0 Writes register
++ * ERAL 1 00 10XXXXXX Erase all registers
++ * WRAL 1 00 01XXXXXX D15 - D0 Writes to all registers
++ * EWDS 1 00 00XXXXXX Disables all programming
++ * instructions
++ * *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.
