• Manufacturer Part Number: mc9s12xs128
• Description: Hcs12 Microcontrollers 16-bit Automotive Microcontroller
• Manufacturer: Freescale Semiconductor, Inc

Upon clearing CCIF to launch the Erase Verify D-Flash Section command, the Memory Controller will
verify the selected section of D-Flash memory is erased. The CCIF flag will set after the Erase Verify
D-Flash Section operation has completed.
18.4.2.15 Program D-Flash Command
The Program D-Flash operation programs one to four previously erased words in the D-Flash block. The
Program D-Flash operation will confirm that the targeted location(s) were successfully programmed upon
completion.
