8.22 Erase / Program Resume (7Ah)

The Erase/Program Resume command 7Ah is to restart the Block Erase operation or the Page Program

operation upon an Erase/Program Suspend. The Resume command 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 command 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

command 7Ah is ignored by the device.

Resume command 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 command not to be issued

within a minimum of time of tSUS following a previous Resume command. See Figure 38 and Figure 39.
