Program/Erase Resume (7Ah)

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

/Block Erase operation after the Program/Erase Suspend. The Program/Erase Resume instruction “7Ah”

will be accepted by the device only if the SUS bit in the Status Register equals to 1 and the WIP bit equals

to 0. After issued the SUS bit will be cleared from 1 to 0 immediately, the WIP bit will be set from 0 to 1

within 200ns and the Page, Sector or 32/64KBlock will complete the program/erase operation. If the SUS

bit equals to 0 or the WIP bit equals to 1, the Program/Erase Resume instruction “7Ah” will be ignored by

the device. The Program/Erase Resume instruction sequence is shown in Figure34.

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

interrupted by unexpected power off. It is also required that a subsequent Program/Erase Suspend

instruction not to be issued within a minimum of time of “tSUS” following a previous Resume instruction.
