Program Suspend Status (bit 2)
The Program Suspend Status bit indicates that a Program operation has been suspended
and is waiting to be resumed. The Program Suspend Status should only be considered valid
when the Program/Erase Controller Status bit is set to ‘1’ (Program/Erase Controller
inactive); after a Program/Erase Suspend command is issued the memory may still
complete the operation rather than entering the Suspend mode.
When the Program Suspend Status bit is set to ‘0’, the Program/Erase controller is active or
has completed its operation; when the bit is set to ‘1’, a Program/Erase Suspend command
has been issued and the memory is waiting for a Program/Erase Resume command.
When a Program/Erase Resume command is issued the Program Suspend Status bit
returns to ‘0’.
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 protected block.
When the Block Protection Status bit is set to ‘0’, no Program or Erase operations have
been attempted to protected blocks since the last Clear Status Register command or
hardware reset; when the Block Protection Status bit is set to ‘1’, a Program or Erase
operation has been attempted on a protected block.
Once set to ‘1’, the Block Protection Status bit can only be reset Low by a Clear Status
Register command or a hardware reset. If set to ‘1’ it should be reset before a new Program
or Erase command is issued, otherwise the new command will appear to fail.
Bit 0
Reserved bit (set to ‘1’).
