Partition0-Erase
The Partition0-Erase command erases all bytes in memory partition 0. All security bits associated with
Page0-3 are also reset.
Sector-Erase
The Sector-Erase command erases all of the bytes in a sector. The sector size for the flash memory
blocks is 128 Bytes. The selection of the sector to be erased is determined by the contents of SFAH
and SFAL.
