<p>Set event breakpoint. First parameter specifies type of event. See <a
href="#breakpoints">general description of event breakpoints</a> above
about meaning of event identifiers. Second parameter specify if the
breakpoint will be fix (<b>f</b>) or dynamic (<b>d</b>). Third
parameter specifies address. Remember that this is not an instruction
address, it is address of the memory cell where specified event should
occur.
</p>
<p>Forth parameter is optional and it specifies the hit number. It is
1 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>
<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:

<p>Go, start execution. Parameters are optional. First parameter
specifies start address of the execution. By default execution starts
at address specified by actual value of the PC. This can be overridden
by first parameter. If second parameter is specified it places a
dynamic breakpoint at specified address which stops the execution. If
stop address is not given the simulator stops if it reaches a
breakpoint, or the CPU accepts an interrupt and <b>stopit</b> option
is TRUE, or fatal error occurres or <a href="#stop">stop</a> command is
used. Note that first instruction is executed without effect of
breakpoints. It means that if there is a breakpoint at start address
then it will not be hit.

After execution is started the <tt>Simulation started</tt> message
appears with value of PC where the execution started and the simulator
is ready to accept other commands while the simulation is running in
background.
<!--If execution stops the simulator first writes out a number which is
the reason of the stop (this is a diagnostic feature, it will beimproved in future versions). Reason can be:
<dl><dt>0
<dd>There is no reason to stop. This number should never appear.
<dt>1
<dd>Serious error for example unknown instruction code which is
impossible to execute.
<dt>2
<dd>Invalid address used in an instruction. For example indirectaddress is bigger then 127 in 51 type of controller. Execution can be
continued but result will be undefined.
<dt>3
<dd>Stack overflow. Execution can be continued but result will be undefined.
<dt>4
<dd>Breakpoint has been reached.
<dt>5
<dd>Interrupt accepted. It only stops the execution if <b>stopit</b>
option is set to TRUE. See <a href="#sopt">sopt</a> command.

After this diagnostic message the simulator prints out instruction at the PC in disassembled form. See <a href="#dis"><b>dis</b></a>

<p>Searching for specified string in internal RAM area. String is
interpreted from first non-space character until end of the command
including spaces. <b>wi</b> command makes case insensitive search and
<b>Wi</b> can be used to make case sensitive search. Result is a hexa
dump of memory areas that match with specified string. Most of C-style
escape sequences can be used in the string: <tt>\f</tt>, <tt>\n</tt>,
<tt>\r</tt>, <tt>\t</tt>, <tt>\v</tt>, <tt>\a</tt>, <tt>\b</tt>,
<tt>\0</tt>, and <tt>\0xxx</tt> where <tt>xxx</tt> is an octadecimal
number of the code of the character.

This version of the simulator knows about three options. First element
of the list is name of the option (<b>verbose</b>, <b>debug</b> and
<b>stopit</b>). This name can be used to identify the option in
<b>gopt</b> and <a href="#sopt"><b>sopt</b></a> command. Second
element of the list is the value of the option. In this case type of
both options is boolean, their value can be TRUE or FALSE. Third
element is a short description of the option.

<dt><b>debug</b> </dt>
<dd>Debug flag can be set by <b>-V</b> option of the
program to TRUE otherwise its default value is FALSE. If it is TRUE,
the simulator prints out short messages about important events.
</dd>
<dt><b>stopit</b> </dt>
<dd>Setting this option to TRUE (default value is
FALSE) forces execution to stop every time when CPU accepts an

described above but it is used to modify SFR. Other difference is that
first parameter (<b>start</b> address) can be specified by name of SFR
not by address only.

<p>This command can be used to set up output values of external circuits
connected to port pins. If a port bit is used as output to drive
external circuits, do not set corresponding pin bit to zero because
read back value of the port can be false. First parameter must be
number of the port between 0 and 3.
