bit is 1 during the self-timed Write Status Register cycle, and is 0 when it is completed.
When the cycle is completed, the Write Enable Latch (WEL) is reset.
The Write Status Register (WRSR) instruction allows the user to change the values of the
Block Protect (BP2, BP1, BP0) bits, to define the size of the area that is to be treated as
read-only, as defined in
the user to set or reset the Status Register Write Disable (SRWD) bit in accordance with the

The Write Status Register (WRSR) instruction is not executed once the Hardware Protected
Mode (HPM) is entered.
