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:
Additionally, if the suspended operation was a Block Erase then the following commands are
also accepted:
During an erase suspend the block being erased can be protected by issuing the Block
Protect command. When the Program/Erase Resume command is issued the operation will
complete.
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
