Erase/Write Disable and Enable
(EWDS/EWEN)
The 93XX76A/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 V
CC
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 opera-
tions. Execution of a
READ
instruction is independent of
both the
EWEN
and
EWDS
instructions.

2.7
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 automatically cycle to the next register
and output sequentially.
