Level 2 data breakpoint invert. Inverts 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.
0 No inversion
1 Invert data breakpoint comparators.
Enable level 2 address breakpoint. Setting an L2EA bit enables the corresponding address breakpoint. Clearing all
three bits disables the breakpoint.
Enable level 2 PC breakpoint.
0 Disable PC breakpoint
1 Enable PC breakpoint
Level 2 PC breakpoint invert.
0 The PC breakpoint is defined within the region defined by PBRn and PBMR.
1 The PC breakpoint is defined outside the region defined by PBRn and PBMR.
Level 2 trigger. Determines the logic operation for the trigger between the PC_condition and the (Address_range and
Data) condition where the inclusion of a Data_condition is optional. The ColdFire debug architecture supports the
creation of single or double-level triggers.
0 Level 2 trigger = PC_condition && (Address_range && Data_condition)
1 Level 2 trigger = PC_condition || (Address_range && Data_condition)
Level 1 trigger. Determines the logic operation for the trigger between the PC_condition and the (Address_range and
Data) condition where the inclusion of a Data_condition is optional. The ColdFire debug architecture supports the
creation of single or double-level triggers.
0 Level 1 trigger = PC_condition && (Address_range && Data_condition)
1 Level 1 trigger = PC_condition || (Address_range && Data_condition)
Enable level 1 breakpoint. Global enable for the breakpoint trigger.
0 Disables all level 1 breakpoints
1 Enables all level 1 breakpoint triggers

Address breakpoint inverted. Breakpoint is based outside the
range between ABLR and ABHR.
Address breakpoint range. The breakpoint is based on the
inclusive range defined by ABLR and ABHR.
Address breakpoint low. The breakpoint is based on the
address in the ABLR.
