Program/Erase Suspend command
The Program/Erase Suspend command is used to pause a Program or Block Erase
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 command can be addressed to any bank.
During Program/Erase Suspend the Command Interface will accept the Program/Erase
Resume, Read Array (cannot read the suspended block), Read Status Register, Read
Electronic Signature and Read CFI Query commands. Additionally, if the suspend operation
was Erase then the Clear Status Register, Set Configuration Register, Program, Block Lock,
Block Lock-Down or Block Unlock command will also be accepted. The block being erased
may be protected by issuing the Block Lock or Block Lock-Down commands. Only the blocks
not being erased may be read or programmed correctly. When the Program/Erase Resume
command is issued the operation will complete. Refer to the 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

the Program/Erase Suspend command.
Program/Erase Resume command
The Program/Erase Resume command can be used to restart the Program/Erase Controller
after a Program/Erase Suspend command has paused it. One Bus Write cycle is required to
issue the command. The command can be written 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. If the bank
was in Read Array mode subsequent read operations will output invalid data.
If a Program command is issued during a Block Erase Suspend, then the erase cannot be
resumed until the programming operation has completed. It is possible to accumulate
suspend operations. For example: suspend an erase operation, start a programming
operation, suspend the programming operation then read the array. See
