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 DO pin.
2. The Status Register contents will repeat continuously until CS# terminate the instruction.
3. All sectors may use any address within the sector.
4. The Device ID will repeat continuously until CS# terminate the instruction.
5. The Manufacturer ID and Device ID bytes will repeat continuously until CS# terminate the instruction.
00h on Byte 4 starts with MID and alternate with DID, 01h on Byte 4 starts with DID and alternate with MID.

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), Block Erase (BE), Chip
Erase (CE) 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 or exit from OTP mode to normal mode. 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, Block Erase (BE) and Chip Erase instructions.
