Figure 12. Write Status Register (WRSR) Sequence
Write Status Register (WRSR)
The Write Status Register (WRSR) instruction al-
lows new values to be written to the Status Regis-
ter. Before it can be accepted, a Write Enable
(WREN) instruction must previously have been ex-
ecuted. After the Write Enable (WREN) instruction
has been decoded and executed, the device sets
the Write Enable Latch (WEL).
The Write Status Register (WRSR) instruction is
entered by driving Chip Select (S) Low, followed
by the instruction code and the data byte on Serial
Data Input (D).
The instruction sequence is shown in Figure 12.
The Write Status Register (WRSR) instruction has
no effect on b6, b5, b4, b1 and b0 of the Status
Register. b6, b5 and b4 are always read as 0.
Chip Select (S) must be driven High after the rising
edge of Serial Clock (C) that latches in the eighth
bit of the data byte, and before the next rising edge
of Serial Clock (C). Otherwise, the Write Status
Register (WRSR) instruction is not executed. As
soon as Chip Select (S) is driven High, the self-
timed Write Status Register cycle (whose duration
is t
W
) is initiated. While the Write Status Register
cycle is in progress, the Status Register may still
be read to check the value of the Write In Progress
(WIP) bit. The Write In Progress (WIP) bit is 1 dur-
ing the self-timed Write Status Register cycle, and
is 0 when it is completed. When the cycle is com-
pleted, the Write Enable Latch (WEL) is reset.
The Write Status Register (WRSR) instruction al-
lows the user to change the values of the Block
Protect (BP1, BP0) bits, to define the size of the
area that is to be treated as read-only, as defined
in Table 2.
The Write Status Register (WRSR) instruction also
allows the user to set or reset the Status Register
Write Disable (SRWD) bit in accordance with the
Write Protect (W) signal. The Status Register
Write Disable (SRWD) bit and Write Protect (W)
signal allow the device to be put in the Hardware
Protected Mode (HPM). The Write Status Register
(WRSR) instruction is not executed once the Hard-
ware Protected Mode (HPM) is entered.
The contents of the Status Register Write Disable
(SRWD) and Block Protect (BP1, BP0) bits are fro-
zen at their current values from just before the
start of the execution of Write Status Register
(WRSR) instruction. The new, updated, values
take effect at the moment of completion of the ex-
ecution of Write Status Register (WRSR) instruc-
tion.
