Write Enable (WREN) (06h)

The Write Enable (WREN) instruction (Figure 5) sets the Write Enable Latch (WEL) bit. The Write Enable

Latch (WEL) bit must be set prior to every Page Program (PP), Sector Erase (SE), Bulk Erase (BE) and

Write Status Register (WRSR) instruction.

The Write Enable (WREN) instruction is entered by driving Chip Select (CS#) Low, sending the instruction

code, and then driving Chip Select (CS#) High.

Write Disable (WRDI) (04h)

The Write Disable instruction (Figure 6) resets the Write Enable Latch (WEL) bit in the Status Register to

a 0 or exit from OTP mode to normal mode. The Write Disable instruction is entered by driving Chip

Select (CS#) low, shifting the instruction code “04h” into the DI pin and then driving Chip Select (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, and Bulk Erase instructions.
