ADSP-21262 EZ-KIT Lite Evaluation System Manual
Global Hardware Breakpoint Options
For ADSP-21262 DSPs, the options listed in
Table 2-9
apply to all hard-
ware breakpoints, regardless of their type.
Data Hardware Breakpoints
For ADSP-21262 DSPs, use data breakpoints to break on accesses to
internal memory, IOP registers, the external port (EP), and multiproces-
sor memory space (MMS).
The following actions trigger a data breakpoint:
•
DAG1
access
•
DM()
modifier access
The two data breakpoints are ORed to generate a single data breakpoint
condition.
The
Data
page of the
Hardware Breakpoints
dialog box, which permits
the specification of two data breakpoints, is shown in
Figure 2-3
.
Table 2-9. Global Hardware Breakpoint Options
Option
Description
Skip N Breakpoint
Events
Specifies the number of breakpoint events to be ignored before stopping
the processor. Each time a hardware breakpoint condition occurs, the
count decrements. When the count reaches zero (
0
), the DSP processes the
hardware break. Use this option to count the number of times a break
operation occurs. Breakpoints within the group are ORed together to cre-
ate this condition.
Restore Skip Count
on Break
Enables skip-count decrement as specified in
Skip N Breakpoint Events
.
Restore Skip Count
on Break
Causes the emulator to restore the Skip Count to the value at program
RESTART
. Otherwise, the Skip Count remains at its current value.
AND All Break-
points
ANDs the interrupts to form the composite interrupt. Normally, the group
interrupts are ORed to create a composite interrupt.
