11.2.5 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.

11.2.6 Write Disable (04h)
The Write Disable instruction (Figure 5) resets the Write Enable Latch (WEL) bit in the Status Register to
a 0. The Write Disable instruction is entered by driving /CS low, shifting the instruction code “04h” into the
DI 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.
