10.2.22 Erase Resume (7Ah)

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

an Erase 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. 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 Resume instruction sequence is shown in figure 22.

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

power off. It is also required that a subsequent Erase Suspend instruction not to be issued within a

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