BDM PORT
The BDM port is a 6 pin header compatible with a Motorola Background Debug Mode (BDM)
Pod. This allows the connection of a background debugger for software development,
programming and debugging in real-time without using HCS12 I/O resources. Note that the
MODC option jumper must be correctly configured to apply a BDM cable.
