Data Sheet
Command Definitions
Writing specific address and data commands or sequences into the command register initiates
device operations.
Tab le 18, “Command Definitions,” on page 60 defines the valid register com-
mand sequences. Writing incorrect address and data values or writing them in the improper
sequence may place the device in an unknown state. The system must write the reset command
to return the device to reading array data. Refer to the AC Characteristics section for timing
diagrams.
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 com
-
pleting an Embedded Program or Embedded Erase algorithm.
After the device accepts an Erase Suspend command, the corresponding bank enters the erase-
suspend-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 from any non-erase-suspended sector within the
same bank. See the
“Erase Suspend/Erase Resume Commands” section on page 55 for more
information.
The system must issue the reset command to return a bank to the read (or erase-suspend-read)
mode if DQ5 goes high during an active program or erase operation, or if the bank is in the au
-
toselect mode. See the “Reset Command” section on page 51 for more information.
