FLASH COMMAND DEFINITIONS
Writing specific address and data commands or se-
quences into the command register initiates device op-
page 31 defines the valid register command se-
quences. Writing incorrect address and data values or
writing them in the improper sequence resets the de-
vice to reading array data.
Refer to the AC Characteristics section for timing dia-
grams.
Reading Array Data
The device is automatically set to reading array data
after device power-up. No commands are required to
retrieve data in asynchronous mode. Each bank is
ready to read array data after completing an Embed-
ded Program or Embedded Erase algorithm.
After the device accepts an Erase Suspend command,
the co rresponding bank enters the eras e-su s -
pend-read mode, after which the system can read
data from any non-erase-suspended sector within the
same bank. After completing a programming operation
in the Erase Suspend mode, the system may once
again read array data with the same exception. See
tion on page 30 section for more information.
The system must issue the reset command to return a
bank to the read (or erase-suspend-read) mode if DQ5
