Data
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
should not be considered erased if the ACCERR flag is set upon command completion.
