READING ARRAY DATA  
RESET COMMAND  
Writing the reset command to the device resets the  
device to reading array data. Address bits are don't care  
for this command.  
The device is automatically set to reading array data  
after device power-up. No commands are required to  
retrieve data.The device is also ready to read array data  
after completing an Automatic Program or Automatic  
Erase algorithm.  
The reset command may be written between the se-  
quence cycles in an erase command sequence before  
erasing begins. This resets the device to reading array  
data. Once erasure begins, however, the device ignores  
reset commands until the operation is complete.  
After the device accepts an Erase Suspend command,  
the device enters the Erase Suspend mode. The sys-  
tem can read array data using the standard read tim-  
ings, except that if it reads at an address within erase-  
suspended sectors, the device outputs status data. After  
completing a programming operation in the Erase  
Suspend mode, the system may once again read array  
data with the same exception. See rase Suspend/Erase  
Resume Commands” for more infor-mation on this mode.  
The system must issue the reset command to re-en-  
able the device for reading array data if Q5 goes high, or  
while in the autoselect mode. See the "Reset Command"  
section, next.  
The reset command may be written between the se-  
quence cycles in a program command sequence be-fore  
programming begins. This resets the device to reading  
array data (also applies to programming in Erase  
Suspend mode). Once programming begins,however, the  
device ignores reset commands until the operation is  
complete.  
The reset command may be written between the se-  
quence cycles in an SILICON ID READ command  
sequence. Once in the SILICON ID READ mode, the  
reset command must be written to return to reading array  
data (also applies to SILICON ID READ during Erase  
Suspend).  
If Q5 goes high during a program or erase operation,  
writing the reset command returns the device to read-  
ing array data (also applies during Erase Suspend).
