1.3 Devices Covered in this Document
The MC68HC912DG128A device is similar to the MC68HC912DT128A,
but it has only two MSCAN12 modules. The entire databook applies to
both devices, except where differences are noted.
The MC68HC912DT128C and MC68HC912DT128P are devices similar
to the MC68HC912DT128A, but with different oscillator configurations.
Sections of this book applicable to the MC68HC912DT128A also apply
to the MC68HC912DT128C and MC68HC912DT128P, except for the
differences highlighted in Section 13. Oscillator.
The MC68HC912DG128C and MC68HC912DG128P are devices
