Write Enable (WREN) (06h)
The Write Enable (WREN) instruction (Figure 5)
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.

sets the Write Enable Latch (WEL) bit. The Write Enable
Write Disable (WRDI) (04h)
The Write Disable instruction (Figure 6) resets the Write Enable Latch (WEL) bit in the Status Register to
a 0. 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.
Read Status Register (RDSR) (05h)
The Read Status Register (RDSR) instruction allows the Status Register to be read. The Status Register
may be read at any time, even while a Program, Erase or Write Status Register cycle is in progress.
When one of these cycles is in progress, it is recommended to check the Write In Progress (WIP) bit
before sending a new instruction to the device. It is also possible to read the Status Register continuously,
as shown in Figure 7.
