64 KByte Flash Module (S12XFTMR64K1V1)
S12XS Family Reference Manual, Rev. 1.13
652 Freescale Semiconductor
CAUTION
A 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 D-Flash command, the user-supplied words will be transferred
to the Memory Controller and be programmed if the area is unprotected. The CCOBIX index value at
Program D-Flash command launch determines how many words will be programmed in the D-Flash block.
The CCIF flag is set when the operation has completed.
20.4.2.16 Erase D-Flash Sector Command
The Erase D-Flash Sector operation will erase all addresses in a sector of the D-Flash block.
