Purpose of the
H8/3003 Emulator

The H8/3003 Emulator is designed to replace the H8/3003
microproc e ssor in your tar ge t system so you can cont rol operation of
the microproc essor i n your appli cat ion hardwa re (usuall y refe r
to as the target system). The H8/3003 emulator perf orms just like the
H8/3003 micropro cessor , but is a device that allows yo u to control the
H8/3003 micropro ce ssor direc tly. These feat ure s a llow you t o easi ly
debug softwa re be for e any hardware i s ava ila bl e, and e ase th e task of
integrating hardware and software.

Emulation memory The H8/3003 emulator is used with one of the following Emulation

Memory Cards.

HP 64726A 128K byte Emula tion Me mo ry Card
HP 64727A 512K byte Emula tion Me mo ry Card
HP 64728A 1M byte Emula t ion Memory Card
HP 64729A 2M byte Emula t ion Memory Card

You can defin e up to 16 me mo ry ranges (at 512 byte bo unda ri e s and
least 512 byt e in le ngt h. ) The em ula t or oc c upi es 6K byte, which is
used for monitor pro gram and interna l RAM of micr o proc e ssor ma ppe d
as emulation RAM, leaving 1 22K, 506K, 1018K, 2042K byte of
emulati on m emo ry which you may use. You can chara c teri z e me mo ry
range as emul atio n RAM (e ra m), em ulat ion ROM (er om ), target
system RAM (tram), tar get system ROM (trom ), or guard ed mem ory
(grd). The emulator gene ra tes an error messa ge when acc esse s are
made to guarde d m emo ry lo ca t ion s. You can al so configure the
emulator so that writes t o memory def ined as ROM cause e mula to r
execu tion to break out of targe t pr ogra m ex ecution.

Analysis The H8/3003 emulator is used with one of the following analyzers

Getting Started

Introduction This chapt er will lea d you through a basic , step by ste p tutor ia l

designed to familiari z e you with the use of the HP 64700 emula tor for
the H8/3003 micropr oc esso r. When you have compl ete d this chap ter,
you will be able to perform these tasks:

Set up an emulation configuration for out of circuit emulation
use

Map memory

Transfer a small prog ram into emul atio n mem ory

Use run/stop con tro ls to contro l opera t ion of your progr am

Use memory m a nip ula t ion features to a lte r the pro gra m ’s
operat ion

2

Use analyzer comma nds to view the rea l time exe c ution of
your program

Use software breakpoint feature to stop program execution at
speci fic address

Search mem ory fo r strings or num eric expre ssio n s

Make progr am coverage me a surements

Getting Started 2-1

Before You Begin Before be gi nni ng t he tut ori al pre se nte d i n thi s ch ap te r, you must have

completed the following tasks:

1. Complete d ha rdwa re in sta lla ti on of t he HP 64700 e m ula tor in
the configu ra ti on you inten d to use for your wor k:

Standalon e configuration
Transparent confi guration
Remote conf igu ra ti on

2. If you are using t he Remot e Confi gur at io n, you must ha ve
completed installation and configuration of a terminal
emulator prog ra m whic h wil l allow your host t o act as a
terminal connecte d t o the emu la to r. In addit ion , yo u mu st sta rt
the termina l em ula tor program bef ore you ca n work the
example s in this c ha pt er .

3. If you have prope rl y c om ple t ed ste ps 1 an d 2 ab ove , you
should be able to hit <RETURN> (or <ENTER> on some
keyboar ds) and ge t on e of the fol lowi ng c om m an d prompt s on
your terminal screen:

U>
R>
M>

If you do not see one of the se c om m an d prom pt s, retrace yo ur
steps throu gh the hardware and softwa re inst a llat ion
proced u re s outl ined in the ma nuals abov e, ve ri fying all
connecti ons a nd pr oc ed ura l step s. If you ar e stil l unabl e to get
a command prompt, refer to the HP 64700 Support Service s
Guide. The guid e give s basic troubl esh ooting proce dure s. If
this fail s, call the lo cal HP sale s a nd se rvice office list e d in the
Support Services Guide.

2-2 Getting Started

In any case, you must have a comm and prompt on your
terminal screen bef ore proc e e din g wit h the tu tor ia l.

A Look at the
Sample Program

The sample progra m "COMMAND_READE R" use d in this chapt e r is
shown figure 2-1. The program emulates a primitive command
interpreter.

Data Declarations

Msg_A, Msg_B and Msg_I are the messa ges use d by the progra m to
respond to various c om man d inp uts.

Initializ atio n

The locati ons of st ac k and i nput area (C md _Inp ut) are move d in to
address re gisters for u se by the program. Next, the CLEAR routine
clears the c om mand byte (t he first lo ca tion pointed to by Cmd_In put ­0ff800 hex) . Cmd_ Inpu t cont ai ns 00 hex fo r late use.

Scan

This routine conti nuo usly reads t he byte at loca tion of Cmd_Input until
it is something ot he r th an a null cha ra cte r (00 hex); whe n this oc c urs,
the Exe _Cm d routine is executed.

Exe_Cmd

Compare s th e i nput byt e (now something ot her than a null) t o the
possible comman d bytes of "A" (ASCII 41 hex) and "B" (ASCII 42
hex), then jum ps to the approp ria t e set up routine for the command
message. If the input byte does not ma tch either of these values, a
branch to a set up routine for an error message is executed.

Cmd_A, Cmd_B, Cmd_I

These ro uti ne s set up the prope r pa ra m et ers for writing the outp ut
message: the numbe r of byte s in the messa ge is move d to the R3L
register and the base address of th e messag e in the data are a is moved
to address register ER4.

Getting Started 2-3

Write_Msg

First the base address of the output area is copied to ER5. Then the
Clear_ Old ro uti ne writes null s to 32 byte s of t he outp ut a re a (thi s
serves bot h to initia liz e the area a nd to clea r old messa ge s wri tt en
during previo us prog ra m passe s).

Finally, the prope r me ssag e is writte n to the out put area by the
Write_Loop routi ne . When do ne , Wri te _L oop jumps bac k to Cle ar and
the comman d mo nitoring process be gi ns a ga in.

Using the various fea tur es of the emula tor , we wil l show you how to
load this p rogram into emulation me mory, exe cute it, monitor the
program ’s ope ra ti on with the anal yz er, and simu late entry of different
command s uti li zing t he mem ory a cce ss c om mand s provi de d by the HP
64700 command set.
