Modes of Operation
Read Mode
The flash memory has four read modes (read array, read identifier, read status, and CFI
query) and two write modes (program and erase). Three additional modes (erase
suspend to program, erase suspend to read, and program suspend to read) are
available only during suspended operations.

commands used for these modes.

showing the state transitions.
Read Array
When RP# transitions from V
and will respond to the read-control inputs (CE#, address inputs, and OE#) without any
additional CUI commands.
When the device is in read array mode, four control signals control data output.
In addition, the address of the desired location must be applied to the address pins. If
the device is not in read-array mode, as would be the case after a Program or Erase
operation, the Read Array command (0xFF) must be issued to the CUI before array
reads can occur.
Read Identifier
The read-identifier mode outputs three types of information: the manufacturer/device
identifier, the block locking status, and the protection register. The device is switched to
this mode by issuing the Read Identifier command (0x90). Once in this mode, read
cycles from addresses shown in
read-array mode, issue the Read Array command (0xFF).
