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
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..
