Figure 88. Read Status Register instruction sequence QIO-SPI
Write status register (WRSR)
The write status register (WRSR) instruction allows new values to be written to the status
register. Before it can be accepted, a write enable (WREN) instruction must previously have
been executed.
The instruction code and the input data are sent on four pins DQ0, DQ1, DQ2 and DQ3. The
instruction functionality is exactly the same as the Write Status Register (WRSR) instruction
of the Extended SPI protocol (See
the protection feature management is different. In particular, once SRWD bit is set to '1' the
device enters in the hardware protected mode (HPM) independently from Write Protect
(W/VPP) signal value. To exit the HPM mode is needed to switch temporarily to the
Extended SPI protocol.
