Debug Support
5.4.7
The TDR, shown in
with the ABHR/ABLR/AATR, PBR/PBMR, and DBR/DBMR registers within the debug module. The
TDR controls the actions taken under the defined conditions. Breakpoint logic may be configured as a one-
or two-level trigger. TDR[31–16] define the second-level trigger and bits 15–0 define the first-level
trigger.
A write to TDR clears the CSR trigger status bits, CSR[BSTAT].

The debug module has no hardware interlocks, so to prevent spurious
breakpoint triggers while the breakpoint registers are being loaded, disable
TDR (by clearing TDR[29,13])before defining triggers.

Enable breakpoint. Global enable for the breakpoint trigger. Setting TDR[EBL] enables a breakpoint trigger.
Clearing it disables all breakpoints at that level.
