Data Sheet
Write-Disable (WRDI)
The Write-Disable (WRDI) instruction resets the Write-Enable-Latch bit and AAI bit to 0 disabling any
new Write operations from occurring. The WRDI instruction will not terminate any programming opera-
tion in progress. Any program operation in progress may continue up to T BP after executing the WRDI
instruction. CE# must be driven high before the WRDI instruction is executed.

Enable-Write-Status-Register (EWSR)
The Enable-Write-Status-Register (EWSR) instruction arms the Write-Status-Register (WRSR)
instruction and opens the status register for alteration. The Write-Status-Register instruction must be
executed immediately after the execution of the Enable-Write-Status-Register instruction. This two-
step instruction sequence of the EWSR instruction followed by the WRSR instruction works like SDP
(software data protection) command structure which prevents any accidental alteration of the status
register values. CE# must be driven low before the EWSR instruction is entered and must be driven
high before the EWSR instruction is executed.
