Version 1 ColdFire Debug (CF1_DEBUG)
26.3.9
The ABLR and ABHR define regions in the processor’s data address space that can be used as part of the
trigger. These register values are compared with the address for each transfer on the processor’s high-speed
local bus. The trigger definition register (TDR) identifies the trigger as one of three cases:
The address breakpoint registers are accessible in supervisor mode using the WDEBUG instruction and
through the BDM port using the WRITE_DREG command using values shown in
Command Set Descriptions.”

Version 1 ColdFire core devices implement a 24-bit, 16 MB address map.
When programming these registers with a 32-bit address, the upper byte
must be zero-filled.
