Datasheet

allowed during an ERASE SUSPEND state. When the ERASE operation resumes, it does

not check the new lock status of the WRITE LOCK REGISTER command.

During a PROGRAM SUSPEND operation, a READ operation is possible in any page ex-

cept the one in a suspended state. Reading from a page that is in a suspended state will

output indeterminate data. The commands allowed during a program suspend state in-

clude the WRITE VOLATILE CONFIGURATION REGISTER command and the WRITE

ENHANCED VOLATILE CONFIGURATION REGISTER command.

It is possible to nest a PROGRAM/ERASE SUSPEND operation inside a PROGRAM/

ERASE SUSPEND operation just once. Issue an ERASE command and suspend it. Then

issue a PROGRAM command and suspend it also. With the two operations suspended,

the next PROGRAM/ERASE RESUME command resumes the latter operation, and a sec-

ond PROGRAM/ERASE RESUME command resumes the former (or first) operation.
