+used to check value of bit or bits.
+
+
+<a name="dump_memory"><h4>dump memory_type [start [end
+[bytes_per_line]]]</h4></a>
+
+Hexadecimal dump of a memory region. First parameter specifies
+memory. Class name of the memory must be used, it can be checked using
+<a href="cmd_general.html#conf">conf</a> command which lists size and
+class 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 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.

-First lines on the list (labeled with Px) are value of SFRs which are
-internal latch registers. Second lines (labeled with Pinx) are outputs
-of external devices connected to port pins of the
-microcontroller. These values can be set by you using <a
-href="#sp"><b>sp</b></a> command. Third lines (labeled with Portx)
-show actual values can be measured on pins of the device. These values
-are calculated with following pseudo formula:
-
-<p><tt>Portx= Px AND Pinx</tt>
-
-<p>All three values are displayed in binary, hexadecimal, decimal form
-and then the ASCII character of the value is shown.

-Print out SFR. This command can be used to get value of all or some
-SFRs. If you do not specify any parameter the <b>ds</b> command simply
-dumps out full SFR area 16 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:
