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” is accepted by the device only if the SUS bit in the

Status Register equals to 1 and the BUSY bit equals to 0. After the instruction is issued, the SUS bit is cleared

immediately, the BUSY bit is set within 200 ns, and the block completes the erase operation, or the page completes the

program operation. If the SUS bit equals to 0 or the BUSY bit equals 1, the Resume instruction “7Ah” is 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. Refer to Figure 7-35 and Figure 7-36 below.
