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

and any other commands can't be inserted between them. Otherwise, Write Enable for Volatile Status

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