Write Disable (WRDI) (04H)
The Write Disable command is for resetting the Write Enable Latch (WEL) bit. The Write Disable command sequence:
CS# goes low Sending the Write Disable command CS# goes high. The WEL bit is reset by following condition: Power-
up and upon completion of the Write Status Register, Page Program, Sector Erase, Block Erase, Chip Erase,
Erase/Program Security Registers and Reset commands.
