Write Enable (WREN) (06H)
The Write Enable (WREN) command is for setting the Write Enable Latch (WEL) bit. The Write Enable Latch (WEL)
bit must be set prior to every Page Program (PP), Sector Erase (SE), Block Erase (BE), Chip Erase (CE), Write Status
Register (WRSR) and Erase/Program Security Registers command. The Write Enable (WREN) command sequence: CS#
goes low  sending the Write Enable command  CS# goes high.
