4.10 Program/Erase Suspend command
The Program/Erase Suspend command is used to pause a Program or Block Erase operation.
The command can be addressed to any bank.
The Program/Erase Resume command is required to restart the suspended operation.
One bus write cycle is required to issue the Program/Erase Suspend command. Once the
Program/Erase Controller has paused bits SR7, SR6 and/ or SR2 of the Status Register will be
set to ‘1’.
The following commands are accepted during Program/Erase Suspend:
Program/Erase Resume
Read Array (data from erase-suspended block or program-suspended Word is not valid)
Read Status Register
Read Electronic Signature
Read CFI Query.
In addition, if the suspended operation was a Block Erase then the following commands are
also accepted:
Clear Status Register
Program (except in erase-suspended block)
Buffer Program (except in erase suspended blocks)
It is possible to accumulate multiple suspend operations. For example: suspend an erase
operation, start a program operation, suspend the program operation, then read the array.
If a Program command is issued during a Block Erase Suspend, the erase operation cannot be
resumed until the program operation has completed.
The Program/Erase Suspend command does not change the read mode of the banks. If the
suspended bank was in Read Status Register, Read Electronic signature or Read CFI Query
mode the bank remains in that mode and outputs the corresponding data.
Refer to Dual Operations section for detailed information about simultaneous operations
allowed during Program/Erase Suspend.
During a Program/Erase Suspend, the device can be placed in standby mode by taking Chip
Enable to V
IH
. Program/erase is aborted if Reset, RP, goes to V
IL
.

Appendix C

Figure 21: Program Suspend & Resume Flowchart and Pseudo Code
, and
Figure 23: Erase Suspend & Resume Flowchart and Pseudo Code
, for flowcharts for using the
Program/Erase Suspend command.
4.11 Program/Erase Resume command
The Program/Erase Resume command is used to restart the program or erase operation
suspended by the Program/Erase Suspend command. One Bus Write cycle is required to issue
the command. The command can be issued to any address.
The Program/Erase Resume command does not change the read mode of the banks. If the
suspended bank was in Read Status Register, Read Electronic signature or Read CFI Query
mode the bank remains in that mode and outputs the corresponding data.
