ERASE/WRITE DISABLE And ENABLE (EWDS/EWEN)
The 93XX66A/B/C powers up in the ERASE/WRITE
Disable (
EWDS
) state. All Programming modes must be
preceded by an ERASE/WRITE Enable (
EWEN
) instruc-
tion. Once the
EWEN
instruction is executed, program-
ming 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 indepen-
dent 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 (T
PD
). Sequential read is possible
when CS is held high. The memory data will automati-
cally cycle to the next register and output sequentially.
