Write Enable (WREN)
The Write Enable Latch (WEL) bit must be set prior to each WRITE and WRSR instruction.
The only way to do this is to send a Write Enable instruction to the device.
As shown in
and the bits of the instruction byte are shifted in, on Serial Data input (D). The device then
enters a wait state. It waits for a the device to be deselected, by Chip Select (S) being driven
high.

Write Disable (WRDI)
One way of resetting the Write Enable Latch (WEL) bit is to send a Write Disable instruction
to the device.
As shown in
and the bits of the instruction byte are shifted in, on Serial Data input (D).
The device then enters a wait state. It waits for a the device to be deselected, by Chip Select
(S) being driven high.
The Write Enable Latch (WEL) bit, in fact, becomes reset by any of the following events:
