RDX
allows the user to change the
current
Radix. Softpanel starts with

Memory Breakpoints
Using the
SIMB
breakpoint board in conjunction
with
the softpanel allows for breaking on absolute
memory addresses for software debugging or tracing. The breakpoint capability includes two addresses,
designated
as
A and
B.
These addresses can be set up
as
a range, allowing for breakpointing
of
a region of
memory.
A data
pattern
is
al~o
available, which allows fer breaking only on a
particular
pattern
being
written
(read
data patterns are not supported) to a memory word. This
data
pattern
can consist of ones, zeros, and don't
cares.
All memory breakpoint commands require the
51MB
breakpoint board.
