9.2.3 Write Enable (06h)

The Write Enable instruction (Figure 4) sets the Write Enable Latch (WEL) bit in the Status Register to

a 1. The WEL bit must be set prior to every Page Program, Sector Erase, Block Erase, Chip Erase

and Write Status Register instruction. The Write Enable instruction is entered by driving /CS low,

shifting the instruction code “06h” into the Data Input (DI) pin on the rising edge of CLK, and then

driving /CS high.

to a 0. The Write Disable instruction is entered by driving /CS low, shifting the instruction code “04h”

into the DIO pin and then driving /CS high. Note that the WEL bit is automatically reset after Power-up

and upon completion of the Write Status Register, Page Program, Sector Erase, Block Erase and

Chip Erase instructions.
