Read-Array Command
Upon initial device power-up and after exit from reset, the
device defaults to the read array mode. This operation can
also be initiated by writing the Read-Array command. (See
Table 8.) The device remains available for array reads until
another command is written. Once an internal Program/
Erase operation starts, the device will not recognize the
Read-Array command until the operation is completed,
unless the operation is suspended via a Program/Erase
Suspend command.
Read-Software-ID Command
The Read-Software-ID operation is initiated by writing the
Read-Software-ID command. Following the command, the
device will output the manufacturer’s ID and device ID from
the addresses shown in Table 9. Any other valid command
will terminate the Read-Software-ID operation.
The Read-Software-ID command is the same as the Read-
Security-ID command. See “Security ID Commands” on
page 17.

Block Protect Status
The Block Write-Lock bit should be interrogated only after Erase or Program command is issued.
It informs the system whether or not the selected block is locked.
BPS does not provide a continuous indication of Write-Lock bit value.
0: Block Unlocked
1: Operation Aborted, Block Write-Lock bit set.

TABLE 9: Product Identification
Read-Status-Register Command
The Status register may be read to determine when a Sec-
tor-/Block-Erase or Program completes, and whether the
operation completed successfully. The Status register may
be read at any time by writing the Read-Status-Register
command. After writing this command, all subsequent
Read operations will return data from the Status register
until another valid command is written.
The default value of the Status register after device power-
up or reset is 80H.
Clear-Status-Register Command
The user can reset the Status register’s Block Protect Sta-
tus (BPS) bit to 0 by issuing a Clear-Status-Register com-
mand. Device power-up and hardware reset will also reset
BPS to 0.
