As the exercises are not intended to be a lesson in typing, the appropriate files
are included within the zip file AN2616SW.zip. The files main.c and
M68DEMO908GB60.h are contained in the relevant sub directory within the zip
file, and can simply be dragged from the zip file into the Sources directory of
the CodeWarrior project at the appropriate point. For example, the directory 2.4
within the zip file contains the correct files for section 2.4. Alternatively, the
code can be copied from an electronic copy (pdf) of the application note, and
pasted into the relevant file using the CodeWarrior editor.
The HCS08 is Motorola’s latest range of 8-bit low-power, high-performance
microcontrollers based on the HC08 core. The major differences from the
HC08 are as follows.
Instruction cycle timings have changed on some instructions/addressing
modes due to design requirements to enable higher frequency operation and
care should be exercised with time critical code that was used on an HC08.
