    Erase/Write Disable and Enable
    (EWDS/EWEN)
    The 93XX46A/B/C powers up in the Erase/Write Disable
    (EWDS) state. All programming modes must be preceded
    by an Erase/Write Enable (EWEN) instruction. Once the
    EWEN
    instruction is executed, programming remains
    enabled until an EWDS instruction is executed or Vcc is
    removed from the device.
    To protect against accidental data disturbance, the EWDS
    instruction can be used to disable all erase/write functions
    and should follow all programming operations. Execution
    of a READ instruction is independent of both the EWEN and
    EWDS
    instructions.

    Read
    The READ instruction outputs the serial data of the
    addressed memory location on the DO pin. A dummy
    zero bit precedes the 8-bit (if ORG pin is low or A-version
    devices) or 16-bit (if ORG pin is high or B-version
    devices) output string.
    The output data bits will toggle on the rising edge of the
    CLK and are stable after the specified time delay (TPD).
    Sequential read is possible when CS is held high. The
    memory data will automatically cycle to the next register
    and output sequentially.
