134 internal latch registers. Second lines (labeled with Pinx) are outputs
135 of external devices connected to port pins of the
136 microcontroller. These values can be set by you using <a
137 href="#sp"><b>sp</b></a> command. Third lines (labeled with Portx)
138 show actual values can be measured on pins of the device. These values
139 are calculated with following pseudo formula:
141 <p><tt>Portx= Px AND Pinx</tt>
143 <p>All three values are displayed in binary, hexadecimal, decimal form

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

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

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

430 This version of the simulator knows about three options. First element
431 of the list is name of the option (<b>verbose</b>, <b>debug</b> and

433 <b>gopt</b> and <a href="#sopt"><b>sopt</b></a> command. Second
434 element of the list is the value of the option. In this case type of
435 both options is boolean, their value can be TRUE or FALSE. Third
436 element is a short description of the option.

440 <dt><b>debug</b> <dd>Debug flag can be set by <b>-V</b> option of the

442 the simulator prints out short messages about important events.
444 <dt><b>stopit</b> <dd>Setting this option to TRUE (default value is
445 FALSE) forces execution to stop every time when CPU accepts an

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