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:
