Chapter 19 Flash Module (S12ZFTMRZ)MC9S12ZVMB Family Reference Manual Rev. 1.3662 NXP Semiconductors19.4.7.15 Program EEPROM CommandThe 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 programmedupon completion.CAUTIONA Flash word must be in the erased state before being programmed.Cumulative programming of bits within a Flash word is not allowed.Upon clearing CCIF to launch the Program EEPROM command, the user-supplied words will betransferred to the Memory Controller and be programmed if the area is unprotected. The CCOBIX indexvalue at Program EEPROM command launch determines how many words will be programmed in theEEPROM block. The CCIF flag is set when the operation has completed.19.4.7.16 Erase EEPROM Sector CommandThe Erase EEPROM Sector operation will erase all addresses in a sector of the EEPROM block.Table 19-64.
