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 specified 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.  
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.
