21.4.7.14 Erase Verify EEPROM Section Command
The Erase Verify EEPROM Section command will verify that a section of code in the EEPROM is erased.
The Erase Verify EEPROM Section command defines the starting point of the data to be verified and the
number of words.
Upon clearing CCIF to launch the Erase Verify EEPROM Section command, the Memory Controller will
verify the selected section of EEPROM memory is erased. The CCIF flag will set after the Erase Verify
EEPROM Section operation has completed. If the section is not erased, it means blank check failed, both
MGSTAT bits will be set.
21.4.7.15 Program EEPROM Command
The Program EEPROM operation programs one to four previously erased words in the EEPROM block.
The Program EEPROM operation will confirm that the targeted location(s) were successfully programmed
upon completion.
CAUTION
A Flash word must be in the erased state before being programmed.
Cumulative programming of bits within a Flash word is not allowed.
