The Write Enable (WREN) instruction (Figure 7) sets the Write Enable Latch (WEL) bit.
The Write Enable Latch (WEL) bit must be set prior to every Page Write (PW), Page
Program (PP), Page Erase (PE), Sector Erase (SE), Bulk Erase (BE) and Write to Lock

The Write Enable (WREN) instruction is entered by driving Chip Select (S) Low, sending the
instruction code, and then driving Chip Select (S) High.
