-Disassemble code. This command can be used to list disassembled
-instructions which discovered by the code analyzer. 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
-analyzer 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.
+First form can be used get content of memory while second form can be
+used to check value of bit or bits.
-<p>In third parameter you can specify how many instructions you want
-to list. Default value is 20.

+
+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>Last parameter can be used to specify how many memory locations
+should be dumped out in one line. It is 8 by default.

-SFRs. If you do not specify any parameter the <b>ds</b> command simply
-dumps out full SFR area 16 bytes per line.
+Hexadecimal dump of <b>sfr</b> named address space area from address
+<b>start</b> to address <b>stop</b>. Default value of start address is
+address of following memory cell which was dumped by previous
+<b>ds</b> command. If <b>stop</b> parameter is not given <b>ds</b>
+command lists 10 lines 8 bytes per line.

-If you specify one or more parameter the <b>ds</b> command prints out
-value of registers specified by parameters. Parameter can be an
-address or a symbolic name of the register. Note that the simulator
-implements a register at all address in the address space which is not
-true in real microcontroller where reading of an unimplemented
-register gets undefined value. Value of the registers printed out in
-hexadecimal, decimal, and ASCII form.
-
-<p>Note that different type of controllers can implement different
-registers:

-Dump bits. This command can be used to get value of bits. At least one
-parameter must be given. Bit address can be specified in three
-forms. First of all name of the bit can be used if it has any. Direct
-bit address is accepted too and it can be specified by address of IRAM
-or SFR which contains the bit and bit number within the byte separated
-by a dot. If the requested bit is in an SFR the address of the
-register can be specified by its name.

-Value of bits are printed out one per line. The list starts direct
-address of the bit followed by bit name or address of the memory cell
-or SFR which contains the displayed bit and bit number within the byte
-separated by a dot. At last the value of the bit is shown. Displaying
-a port bit you get value of SFR latch:
