Enter the following parameters:
[base_address [top_address] ]
or
[base_address [: byte_count] ]
The top_address must equal or exceed the base_address. Wrap-around
is not permitted. The default for byte_count is 1MB.
You may also enter a special character, either at the prompt or after
typing new data, for
scrolling through register Zn. The special
characters are:
Offset register rules:
At power-up and cold start reset, Z7 is the automatic register.
At power-up and cold start reset, all offset registers have both
base and top addresses preset to 0. This effectively disables
them.
Z7 always has both base and top addresses set to 0; it cannot
be changed.
Any offset register can be set as the automatic register.
The automatic register is always added to every absolute
address argument of every debugger command where there
is not an offset register explicitly called out.
There is always an automatic register. A convenient way to
disable the effect of the automatic register is by setting Z7 as
the automatic register. Note that this is the default condition.
V or v Open the next register. This is the default, and remains in
effect until changed by entering one of the other special
characters.
^ Back up and open the previous register
= Re-open the same register
. Terminate the OF command, and return control to the
debugger
