Except for the sector erase abort command, a buffered command will wait for the active operation to be
completed before being launched. The sector erase abort command is launched when the CBEIF flag is
cleared as part of a sector erase abort command write sequence. After a command is launched, the
completion of the command operation is indicated by the setting of the CCIF flag. The CCIF flag only sets
when all active and buffered commands have been completed.

Data
Verify all memory bytes in the Flash block are erased. If the Flash block is erased, the BLANK
flag in the FSTAT register will set upon command completion.
Compress data from a selected portion of the Flash block. The resulting signature is stored in
the FDATA register.
Program a word (two bytes) in the Flash block.
Erase all memory bytes in a sector of the Flash block.
Erase all memory bytes in the Flash block. A mass erase of the full Flash block is only possible
when FPLDIS, FPHDIS, and FPOPEN bits in the FPROT register are set prior to launching the
command.
Abort the sector erase operation. The sector erase operation will terminate according to a set
procedure. The Flash sector must not be considered erased if the ACCERR flag is set upon
command completion.
