The only other valid commands while block erase is suspended are Read Query, Read Status

command is written to the flash memory, the WSM will continue the block erase process. SR.6 and

SR.7 will automatically clear and STS (in default mode) will return to V

. After the Erase

Resume command is written, the device automatically outputs SRD when read (see

Figure 23,

鈥淏lock Erase Suspend/Resume Flowchart鈥?on page 64).

PEN

must remain at V

PENH

(the same

PEN

level used for block erase) while block erase is suspended. Block erase cannot resume until

program operations initiated during block erase suspend have completed.

12.3

Erase Resume

To resume (i.e., continue) an erase suspend operation, execute the Erase Resume command. The

Resume command can be written to any device address. When a program operation is nested

within an erase suspend operation and the Program Suspend command is issued, the device will

suspend the program operation. When the Resume command is issued, the device will resume the

program operations first. Once the nested program operation is completed, an additional Resume

command is required to complete the block erase operation. The device supports a maximum

suspend/resume of two nested routines. See

Figure 22, 鈥淏lock Erase Flowchart鈥?on page 63.
