7.3. Write Enable for Volatile Status Register (50H)

The non-volatile Status Register bits can also be written to as volatile bits. This gives more flexibility to change the

system configuration and memory protection schemes quickly without waiting for the typical non-volatile bit write cycles or

affecting the endurance of the Status Register non-volatile bits. The Write Enable for Volatile Status Register command

must be issued prior to a Write Status Register command. The Write Enable for Volatile Status Register command will not

set the Write Enable Latch bit, it is only valid for the Write Status Register command to change the volatile Status Register

bit values.
