Notes:
1. Data bytes are shifted with Most Significant Bit first. Byte fields with data in parenthesis “( )” indicate data being read from the device on
the SO pin.
2. The Status Register contents will repeat continuously until CS# terminates the instruction.
3. See Table 8.2, Manufacturer and Device Identification on page 15 for Device ID information.
4. The Device ID will repeat continuously until CS# terminates the instruction.

8.1
Write Enable (06h)
The Write Enable command (Figure 8.1) sets the Write Enable Latch (WEL) bit in the Status Register to a 1,
which enables the device to accept a Write Status Register, program, or erase command.
The WEL bit must be set prior to every Page Program, Sector Erase, Block Erase, Chip Erase, and Write
Status Register command. The host system must first drive CS# low, write the WREN command, and then
drive CS# high.
