Program/Erase Suspend (PES) (75H)

The Program/Erase Suspend command

“75H”, allows the system to interrupt a page program or sector/block erase

operation and then read data from any other sector or block. The Write Status Register command (01H/31H/11H) and

Erase/Program Security Registers command (44H, 42H) and Erase commands (20H, 52H, D8H, C7H, 60H) and Page

Program command (02H, 32H) are not allowed during Program suspend. The Write Status Register command

(01H/31H/11H) and Erase Security Registers command (44H) and Erase commands (20H, 52H, D8H, C7H, 60H) are not

allowed during Erase suspend. Program/Erase Suspend is valid only during the page program or sector/block erase

operation. A maximum of

time of “tsus” (See AC Characteristics) is required to suspend the program/erase operation.

The Program/Erase Suspend command will be accepted by the device only if the SUS2/SUS1 bit in the Status Register

equal to 0 and WIP bit equal to 1 while a Page Program or a Sector or Block Erase operation is on-going. If the SUS2/SUS1

bit equal to 1 or WIP bit equal to 0, the Suspend command will be ignored by the device. The WIP bit will be cleared from 1

to 0 within “tsus” and the SUS2/SUS1 bit will be set from 0 to 1 immediately after Program/Erase Suspend. A power-off

during the suspend period will reset the device and release the suspend state. The command sequence is show in Figure29.
