Erase/Write Disable and Enable
(EWDS/EWEN)
Once the EWEN instruction is executed, programming
remains enabled until an EWDS instruction is executed
or Vcc is removed from the device.
The 93XX56A/B/C powers up in the Erase/Write
Disable ( EWDS ) state. All programming modes must be
preceded by an Erase/Write Enable ( EWEN ) instruction.
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 spec-
ified 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.
