COMMAND DEFINITIONS
Writing specific address and data commands or se-
quences into the command register initiates device op-
erations. Tables
command sequences. Writing incorrect address and
data values or writing them in the improper se-
quence may place the device in an unknown state. A
reset command is then required to return the device to
reading array data.
All addresses are latched on the falling edge of WE#
or CE#f, whichever happens later. All data is latched
on the rising edge of WE# or CE#f, whichever hap-

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
