Airaudi Applications Engineering, Microcontroller Division Austin, Texas Introduction This application note describes the basic operation of the background debug mode (BDM) and some of its applications, as it relates to Motorola’s M68HC12 Family of microcontrollers (MCU). Examples of incircuit programming of internal FLASH memory and in-circuit debugging, using P&E Microputer Systems’ BDM interface cable and its software, are also contained in this document. The BDM’s main purpose is to allow debugging...
