Command Definitions  
Writing specific address and data commands or sequences into the command register initiates  
device operations. Table 17 on page 38 defines the valid register command sequences. Writing  
incorrect address and data values or writing them in the improper sequence resets the de-  
vice to reading array data.  
All addresses are latched on the falling edge of WE# or CE#, whichever happens later. All data is  
latched on the rising edge of WE# or CE#, whichever happens first. Refer to the appropriate tim-  
ing diagrams in the “AC Characteristics” section.  
Reading Array Data  
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 Embed-  
ded Program or Embedded Erase algorithm.  
After the device accepts an Erase Suspend command, the device enters the Erase Suspend mode.  
The system can read array data using the standard read timings, except that if it reads at an ad-  
dress 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 Erase Suspend/Erase Resume Commands on page 35 for more in-  
formation on this mode.  
The system must issue the reset command to re-enable the device for reading array data if DQ5  
goes high, or while in the autoselect mode. See the Reset Command on page 32 section, next.  
See also Requirements for Reading Array Data on page 11 for more information. The Read  
Operations on page 50 provides the read parameters, and Figure 14, on page 50 shows the timing  
diagram.
