Program/Erase Suspend command
The Program/Erase Suspend command can be used to pause a Program or Erase operation.
One Bus Write cycle is required to issue the Program/Erase Suspend command and pause
the Program/Erase Controller. Once the command is issued it is necessary to poll the
Program/Erase Controller Status bit to find out when the Program/Erase Controller has
paused; no other commands will be accepted until the Program/Erase Controller has
paused. After the Program/Erase Controller has paused, the memory will continue to output
the Status Register until another command is issued.
During the polling period between issuing the Program/Erase Suspend command and the
Program/Erase Controller pausing it is possible for the operation to complete. Once
Program/Erase Controller Status bit indicates that the Program/Erase Controller is no longer
active, the Program Suspend Status bit or the Erase Suspend Status bit can be used to
determine if the operation has completed or is suspended. For timing on the delay between
issuing the Program/Erase Suspend command and the Program/Erase Controller pausing
see
Table 12
.
During Program/Erase Suspend the Read Memory Array, Read Status Register, Read
Electronic Signature and Program/Erase Resume commands will be accepted by the
Command Interface. Additionally, if the suspended operation was Erase then the Program
command will also be accepted; only the blocks not being erased may be read or
programmed correctly.
See
Figure 19: Program Suspend & Resume flowchart and pseudo code
, and
Figure 21:
Erase Suspend & Resume flowchart and pseudo code
, for suggested flowcharts on using
the Program/Erase Suspend command.
4.8
Program/Erase Resume command
The Program/Erase Resume command can be used to restart the Program/Erase Controller
after a Program/Erase Suspend operation has paused it. One Bus Write cycle is required to
issue the Program/Erase Resume command. Once the command is issued subsequent Bus
Read operations read the Status Register.
