The Device Guide provides information about the MC9S12DT256 device made up of standard HCS12
blocks and the HCS12 processor core.
This document is part of the customer documentation. A complete set of device manuals also includes the
HCS12 Core User Guide and all the individual Block Guides of the implemented modules. In a effort to
reduce redundancy all module specific information is located only in the respective Block Guide. If
applicable, special implementation details of the module are given in the block description sections of this
document.
See Table 0-2 for names and versions of the referenced documents throughout the Device User Guide.
