1.7.2. Write Enable Operation (06h)

When you enable the write enable operation, the write enable latch bit is set to 1 in

the status register. You must execute this operation before the write bytes, write

status, erase bulk, erase sector, extended dual input fast write bytes, extended quad

input fast write bytes, 4BYTEADDREN, and 4BYTEADDREX operations.

1.7.3. Write Disable Operation (04h)

The write disable operation resets the write enable latch bit in the status register. To

prevent the memory from being written unintentionally, the write enable latch bit is

automatically reset when implementing the write disable operation, and under the

following conditions:

•

Power up

•

Write bytes operation completion

•

Write status operation completion

•

Erase bulk operation completion

•

Erase sector operation completion

•

Extended dual input fast write bytes operation completion

•

Extended quad input fast write bytes operation completion
