5.5
The ColdFire Family implements a low-level system debugger in the microprocessor hardware.
Communication with the development system is handled through a dedicated, high-speed serial command
interface. The ColdFire architecture implements the BDM controller in a dedicated hardware module.
Although some BDM operations, such as CPU register accesses, require the CPU to be halted, other BDM
commands, such as memory accesses, can be executed while the processor is running.

Setting an EDx bit enables the corresponding data breakpoint condition based on the size and placement
on the processor’s local data bus. Clearing all EDx bits disables data breakpoints.

Data breakpoint invert. Provides a way to invert the logical sense of all the data breakpoint comparators.
This can develop a trigger based on the occurrence of a data value other than the DBR contents.
Enable address bits. Setting an EA bit enables the corresponding address breakpoint. Clearing all three bits
disables the breakpoint.
EAI

EAL
Enable PC breakpoint. If set, this bit enables the PC breakpoint.
Breakpoint invert. If set, this bit allows execution outside a given region as defined by PBR and PBMR to
enable a trigger. If cleared, the PC breakpoint is defined within the region defined by PBR and PBMR.

Data longword. Entire processor’s local data bus.
Lower data word.
Upper data word.
Lower lower data byte. Low-order byte of the low-order word.
Lower middle data byte. High-order byte of the low-order word.
Upper middle data byte. Low-order byte of the high-order word.
Upper upper data byte. High-order byte of the high-order word.
Enable address breakpoint inverted. Breakpoint is based outside the range between ABLR and
ABHR.
Enable address breakpoint range. The breakpoint is based on the inclusive range defined by
ABLR and ABHR.
Enable address breakpoint low. The breakpoint is based on the address in the ABLR.
