Write Status Register (WRSR) (01H)

The Write Status Register (WRSR) command allows new values to be written to the Status Register.

Before it can be accepted, a Write Enable (WREN) command must previously have been executed. After

the Write Enable (WREN) command has been decoded and executed, the device sets the Write Enable

Latch (WEL).

The Write Status Register (WRSR) command has no effect on S15, S13, S12, S11, S1 and S0 of the

Status Register. CS# must be driven high after the eighth bit of the data byte has been latched in. If not,

the Write Status Register (WRSR) command is not executed. If CS# is driven high after eighth bit of the

data byte, the CMP and QE bit will be cleared to 0.
