<
/a> Hexadecimal dump of a memory region. First parameter specifies
memory. It can be
name of an address space or a chip, and can be
checked
using <
a href="cmd_general.html#info_memory">info memory<
/a> command
which lists
size and
name of all available memories.
<
p><
b>start<
/b> and <
b>end<
/b> parameters can be used to specify the
first and last address of the dumped region. If <
b>end<
/b> is omitted
then
64 memory location is dumped. If both <
b>start<
/b> and <
b>end<
/b>
are omitted then next
64 memory location will be dumped out. Every time
when dump command is used the address of last dumped memory location is
stored and next dump command automatically continues at next address. <
/p>
<
p>Last parameter can be used to specify how many memory locations should
be dumped out in one line. It is
8 by default. <

<
/a> Disassemble
code. This command can be used to list disassembled
instructions which discovered by the <
a href="analyzer.html">
code analyser<
/a>.
First two parameters specify the address where the list starts. First
parameter is address where the command starts to search an instruction. This
search goes forward. When the first instruction marked by
code analyser
found the simulator skips as many instructions as you specify in second
parameter. If <
b>offset<
/b> is negative the simulator goes backward and
skips specified number of instructions. Default
value of <
b>start<
/b>
parameter is last address which was listed by previous <
b>dis<
/b> command
and default
value of <
b>offset<
/b> is -
1. It means you can make continuous
list repeating parameterless <
b>dis<
/b> command.
<
p>In third parameter you can specify how many instructions you want to
list. Default
value is
20. <
