Page 15: What Is Dbug
CHAPTER 2 Freescale Semiconductor, Inc. USING THE MONITOR/DEBUG FIRMWARE The M5206eLITE Computer Board has a resident firmware package that provides a self-contained programming and operating environment.

This Chapter is a description of the dBUG package, including the user interface and command structure. -
Page 16: Operational Procedure
All control registers on ColdFire® are readable only via the supervisor-programming model, and thus not accessible Freescale Semiconductor, Inc. via dBUG. User code may change these registers, but caution must be exercised as changes may render dBUG useless. A reference to “SP” actually refers to “A7”. -
Page 17: System Initialization
2.2.2. System Initialization Freescale Semiconductor, Inc. The act of powering up the board will initialize the system. The processor is reset and dBUG is invoked. dBUG performs the following configurations of internal resources during the initialization. The instruction cache is invalidated and disabled. The Vector Base Register, VBR, points to the Flash. However, a copy of the exception table is made at address $30000000 in FSRAM. -
