Debug interface signals
Entry into debug state on breakpoint
Breakpointed instruction
DBGIEBKPT
INSTR[31:0]
DBGACK
IA[31:1]
CLK
There are four primary external signals associated with the debug interface:
•
•
An instruction being fetched from memory is sampled at the end of a cycle. To apply a
breakpoint to that instruction, the breakpoint signal must be asserted by the end of the
same cycle. This is shown in Figure 7-4.
You can build external logic, such as additional breakpoint comparators, to extend the
breakpoint functionality of the EmbeddedICE-RT logic. You must apply their output to
the DBGIEBKPT input. This signal is ORed with the internally-generated Breakpoint
signal before being applied to the ARM9E-S core control logic.
The timing of the DBGIEBKPT input makes it unlikely that data-dependent external
breakpoints are possible.
F1
DBGIEBKPT, DBGDEWPT, and EDBGRQ are system requests for the
ARM9E-S to enter debug state
DBGACK is used by the ARM9E-S to flag back to the system that it is in debug
state.
