The system must write the reset command to exit the  
"Silicon-ID Read Command" code.  
CHIP UNPROTECT  
TheMX29LV160BT/BBalsofeaturesthechipunprotect  
mode, so that all sectors are unprotected after chip  
unprotectiscompletedtoincorporateanychangesinthe  
code. It is recommended to protect all sectors before  
activating chip unprotect mode.  
Toactivatethismode,theprogrammingequipmentmust  
forceVIDoncontrolpinOEandaddresspinA9. TheCE  
pins must be set at VIL. Pins A6 must be set to VIH.  
Refer to chip unprotect algorithm and waveform for the  
chip unprotect algorithm. The unprotection mechanism  
begins on the falling edge of the WE pulse and is  
terminated on the rising edge.  
It is also possible to determine if the chip is unprotected  
in the system by writing the Read Silicon ID command.  
PerformingareadoperationwithA1=VIH,itwillproduce  
00H at data outputs(Q0-Q7) for an unprotected sector.  
It is noted that all sectors are unprotected after the chip  
unprotect algorithm is completed.
