An EEPROM word (2 bytes) must be in the erased state before being
programmed. Cumulative programming of bits within a word is not allowed.
Sector
Modify
Erase
Mass
Abort
Erase all memory bytes in the EEPROM block. A mass erase of the full EEPROM block is only
possible when EPOPEN and EPDIS bits in the EPROT 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 EEPROM sector should not be considered erased if the ACCERR flag is set
upon command completion.
Erase all four memory bytes in a sector of the EEPROM block and reprogram the addressed
word.
