Table 2-10. Other Hardware Breakpoint Options (Cont'd)
Option Description
External Port Enables external port breakpoints.External port (EP) breakpoints are trig-
gered by accesses made through the External Port. Use an EP breakpoint to
break on accesses made to any external device that may be tied to the EP,
such as external memory.
AND All Break- ANDs the interrupts to form the composite interrupt. Normally, the group
points interrupts are ORed to create a composite interrupt.
Be aware of the following tips and tricks when using hardware breakpoints
on ADSP-21262 processors.
For SHARC processors, hardware breakpoints do not assert until two (2)
instruction cycles after the actual break condition occurs
When using hardware breakpoints, do not place breaks at any address
where a , , or
JUMP CALL IDLE
Do not place breaks in the last few instructions of a
delay slots of a delayed branch. For more information on these illegal loca-
tions, refer to your DSP's Hardware Reference.
To set a breakpoint on a single address, set the Start Address equal to the
End Address.
