Debug Mode
Debug Mode supports application development and debug. Debug mode is available to the
user through the integrated USB-Multilink BDM or the by using an external HCS12 BDM cable.
Use of the integrated USB-Multilink BDM requires only a host PC with an available USB port
and an A/B type USB cable. A 6-pin BDM interface header (BDM_PORT) supports the use of
an external HCS12 BDM cable. The BDM_PORT header is not installed in default configura-
tion. The steps below describe using the integrated USB-Multilink BDM.
1. Connect auxiliary equipment to board as required by application.
2. Install and launch P&E PKG12Z tool set, CodeWarrior Development Studio, or other soft-
ware capable of communicating with the HCS12 MCU.
3. Configure the board option jumpers for DEBUG mode.
