Block Protection Status (Bit 1)
The Block Protection Status bit can be used to identify if a Program or Erase operation has
tried to modify the contents of a locked block.
When the Block Protection Status bit is High (set to ‘1’), a Program or Erase operation has
been attempted on a locked block.
Once set High, the Block Protection Status bit can only be reset Low by a Clear Status
Register command or a hardware reset. If set High it should be reset before a new
command is issued, otherwise the new command will appear to fail.
Reserved (Bit 0)
Bit 0 of the Status Register is reserved. Its value must be masked.
