2.4.1.3.6
The sector erase abort command is used to terminate the sector erase operation so that other sectors in the
Flash block are available for read and program operations without waiting for the sector erase operation
to complete. If the sector erase abort command is launched resulting in the early termination of an active
sector erase operation, the ACCERR flag will set after the operation completes as indicated by the CCIF
flag being set. The ACCERR flag sets to inform the user that the sector may not be fully erased and a new
sector erase 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 operation completes normally, the
ACCERR flag will not set upon completion of the operation as indicated by the CCIF flag being set.
Therefore, if the ACCERR flag is not set after the sector erase abort command has completed, the sector
being erased when the abort command was launched is fully erased. The maximum number of cycles
required to abort a sector erase operation is equal to four FCLK periods (see

Sector Erase Abort Command
Since the ACCERR bit in the FSTAT 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 must 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 FSTAT register will be set. A new
command write sequence may be started after clearing the ACCERR flag, if
set.
The sector erase abort command must be used sparingly because a sector
erase operation that is aborted counts as a complete program/erase cycle.
