3.6
ERASE/WRITE Disable and Enable
(EWEN, EWDS)
The 93LC46/56/66 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 instruc-
tion is executed or VCC is removed from the device. To
protect against accidental data disturb, 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 EWDS and EWEN instructions.
3.7
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 (x8 organization) or 16-bit
(x16 organization) output string. The output data bits
will toggle on the rising edge of the CLK and are stable
after the specied 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.
