A program operation is not allowed to a sector that has been erase suspended. If a program operation is
attempted to an erase suspended sector, then the program operation will abort and the WEL bit in the Status
Register will be reset back to the logical “0” state. Likewise, an erase operation is not allowed to a sector that has
been program suspended. If attempted, the erase operation will abort and the WEL bit in the Status Register will
be reset to a logical “0” state.
During an Erase Suspend, a program operation to a different 64-Kbyte sector can be started and subsequently
suspended. This results in a simultaneous Erase Suspend/Program Suspend condition and will be indicated by
the states of both the ES and PS bits in the Status Register being set to the logical “1” state.
If a Reset operation (see “Reset” on page 40) is performed while a sector is erase suspended, the suspend
operation will abort and the contents of the block in the suspended sector will be left in an undefined state.
However, if a Reset is performed while a sector is program suspended, the suspend operation will abort but only
the contents of the page that was being programmed and subsequently suspended will be undefined. The
remaining pages in the 64-Kbyte sector will retain their previous contents.
If an attempt is made to perform an operation that is not allowed during a program or erase suspend, such as a
Protect Sector operation, then the device will simply ignore the opcode and no operation will be performed. The
state of the WEL bit in the Status Register, as well as the SPRL (Sector Protection Registers Locked) and SLE
(Sector Lockdown Enabled) bits, will not be affected.
