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

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 R eset operation (see “Reset” on page 40) is performed while a s ector is erase suspended, the suspend

operation will abort and t he contents of the block in the suspended sector will be l eft in an u ndefined 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 s ubsequently 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.
