Erase / Program Resume (7Ah)

The Erase/Program Resume instruction “7Ah” is to re-work 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 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 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.

Resume instruction cannot be accepted 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 “t

SUS” following a previous Resume instruction. (Please refer to Figure 7-35 and Figure 7-36).
