Write Enable (WREN)
The Write Enable Latch (WEL) bit must be set pri-
or 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
Figure 8.
, to send this instruction to
the device, Chip Select (S) is driven Low, 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
Figure 9.
, to send this instruction to
the device, Chip Select (S) is driven Low, 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) be-
ing driven High.
The Write Enable Latch (WEL) bit, in fact, be-
comes reset by any of the following events:
–
Power-up
–
WRDI instruction execution
–
WRSR instruction completion
–
WRITE instruction completion.
