Erase/Write Disable and Enable
Once the EWEN instruction is executed, programming
(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.
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.

Read
The output data bits will toggle on the rising edge of the
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.

Sequential read is possible when CS is held high. The
memory data will automatically cycle to the next register
and output sequentially.
