Write-Enable (WREN)

The Write Enable (WREN) instruction sets the Write-

Enable-Latch bit in the Status register to ‘1,’ allowing

Write operations to occur. The WREN instruction must

be executed prior to any of the following operations:

Sector Erase, Block Erase, Chip Erase, Page Program,

Program Security ID, Lockout Security ID, Write Block-

Protection Register, Lock-Down Block-Protection Reg-

ister, Non-Volatile Write-Lock Lock-Down Register, SPI

Quad Page program, and Write-Status Register. To

execute a Write Enable the host drives CE# low then

sends the Write Enable command cycle (06H) then

drives CE# high. See Figures 5-32 and 5-33 for the

WREN instruction sequence.
