COMMAND DEFINITIONS
Writing specific address and data commands or se-
quences into the command register initiates device op-
erations.
register command sequences. Writing incorrect ad-
dress and data values or writing them in the im-
proper sequence, resets the device 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
ing diagrams.

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 ready to read array data
after completing an Embedded Program or Embedded
Erase algorithm.
After the device accepts an Erase Suspend command,
the device enters the erase-suspend-read mode, after
w h i c h t h e s y s t e m c a n r e a d d a t a f r o m a n y
non-erase-suspended sector. After completing a pro-
gramming operation in the Erase Suspend mode, the
system may once again read array data with the same
exception. See
