Unexpected power off during the Erase/Program suspend state will reset the device and release the suspend state.

SUS bit in the Status Register will also reset to 0. The data within the page or block that was being suspended may

become corrupted. It is recommended for the user to implement system design techniques against the accidental

power interruption and preserve data integrity during erase/program suspend state. (Please refer to Figure 7-33 and

Figure 7-34).

7.22 Erase / Program Resume (7Ah)

The Erase/Program Resume instruction “7Ah” is to restart the Block Erase operation or the Page Program operation

upon an Erase/Program Suspend. The Resume instruction

“7Ah” will be accepted by the device only if the SUS bit in

the Status Register equals to 1 and the BUSYbit equals to 0. After issued, the SUS bit will be cleared from 1 to 0

immediately, the BUSY bit will be set from 0 to 1 within 200ns and the Block will complete the erase operation or the

page will complete the program operation. If the SUS bit equals to 0 or the BUSY bit equals to 1, the Resume

instruction “7Ah” will be ignored by the device.
