First lines on the list
(labelled with Px
) are
value of SFRs which are
internal latch registers. Second lines
(labelled 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
(labelled 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>
<

and then the ASCII character of the
value is shown.

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:

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.

name of the option
(<

type of
both options is boolean, their
value can be TRUE or FALSE. Third
