The supplied controller boards for MC68HC908MR32 (ECCTRMR32)
allows two possibilities for software execution:

1. MMDS Evaluation Board (KITMMDSMR32)

Using a real-time debugger (supplied with the Metrowerks
compiler) the evaluation board is connected to the controller board
(ECCTRMR32) via an emulator connector. This solution is
recommended for software evaluation.

2. Programmed MCU (MC68HC908MR32)

Where a daughter board module, with MC68HC908MR32
processor, is plugged into the controller board (ECCTRMR32)
instead of the emulator cable, the processor must be programmed
in an external programmer. This solution is recommended for final
tests.
