7.2.28 Erase / Program Resume (7Ah)

The Erase/Program Resume instruction “7Ah” must be written to resume the Sector or Block Erase

operation or the Page Program operation after 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 BUSY

bit 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 Sector or 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. The Erase/Program Resume instruction sequence is

shown in Figure 26.

Resume instruction is ignored if the previous Erase/Program Suspend operation was interrupted by

unexpected power off. It is also required that a subsequent Erase/Program Suspend instruction not to be

issued within a minimum of time of “tSUS” following a previous Resume instruction.
