16 KByte Flash Module (S12FTMRG16K1V1)
21.4.6.14 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.

Table 21-58. Erase Verify EEPROM Section Command FCCOB Requirements
Field margin levels must only be used during verify of the initial factory
programming.
Field margin levels can be used to check that Flash memory contents have
adequate margin for data retention at the normal level setting. If unexpected
results are encountered when checking Flash memory contents at field
margin levels, the Flash memory contents should be erased and
reprogrammed.
