Write Status Register (WRSR)
This instruction has no effect on bits b7, b6, b5, b4,
b1 and b0 of the Status Register.
As shown in Figure 11., to send this instruction to
the device, Chip Select (S) is first driven Low. The
bits of the instruction byte and data byte are then
shifted in on Serial Data Input (D).
The instruction is terminated by driving Chip Se-
lect (S) High. Chip Select (S) must be driven High
after the rising edge of Serial Clock (C) that latch-
es the eighth bit of the data byte, and before the
the next rising edge of Serial Clock (C). If this con-
dition is not met, the Write Status Register
(WRSR) instruction is not executed. The self-
timed Write Cycle starts, and continues for a peri-
od tW (as specified in Table 18. to Table 22.), at
the end of which the Write in Progress (WIP) bit is
reset to 0.
The instruction is not accepted, and is not execut-
ed, under the following conditions:
if the Write Enable Latch (WEL) bit has not
been set to 1 (by executing a Write Enable
instruction just before)
if a Write Cycle is already in progress
if the device has not been deselected, by Chip
Select (S) being driven High, after the eighth
bit, b0, of the data byte has been latched in
if Write Protect (W) is Low.
