This document contains information for the complete S12XE-Family and thus includes a set of separate
flash (FTM) module sections to cover the whole family. A full list of family members and options is
included in the appendices.
This document contains information for all constituent modules, with the exception of the S12X CPU. For
S12X CPU information please refer to CPU12XV2 in the CPU12/CPU12X Reference Manual.
