1.Write to any EEPROM memory address to start the command write sequence for the sector erase abort command. The address and data written are ignored.

2.Write the sector erase abort command, $47, to the ECMD register.

3.Clear the CBEIF flag in the ESTAT register by writing a “1” to CBEIF to launch the sector erase abort command.

If the sector erase abort command is launched resulting in the early termination of an active sector erase or sector modify operation, the ACCERR flag will set once the operation completes as indicated by the CCIF flag being set. The ACCERR flag sets to inform the user that the EEPROM sector may not be fully erased and a new sector erase or sector modify command must be launched before programming any location in that specific sector. If the sector erase abort command is launched but the active sector erase or sector modify operation completes normally, the ACCERR flag will not set upon completion of the operation as indicated by the CCIF flag being set. If the sector erase abort command is launched after the sector modify operation has completed the sector erase step, the program step will be allowed to complete. The maximum number of cycles required to abort a sector erase or sector modify operation is equal to four EECLK periods (see section 4.1.1) plus five bus cycles as measured from the time the CBEIF flag is cleared until the CCIF flag is set.

NOTE: Since the ACCERR bit in the ESTAT register may be set at the completion of the sector erase abort operation, a command write sequence is not allowed to be buffered behind a sector erase abort command write sequence. The CBEIF flag will not set after launching the sector erase abort command to indicate that a command should not be buffered behind it. If an attempt is made to start a new command write sequence with a sector erase abort operation active, the ACCERR flag in the ESTAT register will be set. A new command write sequence may be started after clearing the ACCERR flag, if set.

NOTE: The sector erase abort command should be used sparingly since a sector erase operation that is aborted counts as a complete program/erase cycle.
