COMMAND DEFINITIONS
Writing specific address and data commands or se-
quences into the command register initiates device op-
erations. Table 14 defines the valid register command
sequences. Writing incorrect address and data values
or writing them in the improper sequence 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#, whichever happens later. All data is latched on
the rising edge of WE# or CE#, whichever happens
first. 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. Each bank is ready to read array data
after completing an Embedded Program or Embedded
Erase algorithm.
After the device accepts an Erase Suspend command,
the corresponding bank enters the erase-sus-
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
