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.

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

Page 24

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.

Transfer Code into Emulation Memory

Transferring Code from a Terminal In

Standalone

Configuration

You must map inte rna l ROM as emu la tion m e mo ry.

You don’t have to map i ntern al RAM, sinc e the emul ator maps in te rna l RAM as emulation RAM. And the emu lato r mem ory syste m dose not introduc e it in mem ory mappi ng di splay.

Refer to "Memory Mapping" section of "Configuring the Emulator" chapte r in thi s ma nu al for m ore de tai ls.

To transfer code into emulation memory from a data terminal running in standalone mode, you must use the modify memory commands. This is necessa ry be c au se yo u have no host compu ter tr an sfe r faci liti es to automati cal ly downlo ad the co de for you (as i f you would if you were using the transp ar en t confi gur at io n or the rem ot e conf igu ra tion. ) To minimiz e the effec t s of typ ing errors, you will modify only one row of memo ry at a time in this example. Do the fol lowi ng:

R> m 002000..00200f=54,48,49,53,20,49,53,20,4d,45,53,53,41,47,45,20 R> m 002010..00201f=41,54,48,49,53,20,49,53,20,4d,45,53,53,41,47,45

2-12 Getting Started

1. Enter the data info rm atio n for the progr am by typi ng th e following commands:

Page 33

R> m 002020..00202f=20,42,49,4e,56,41,4c,49,44,20,43,4f,4d,4d,41,4e R> m 002030=44

You could also t ype the fol lo wing line inste a d:

R> m 002000="THIS IS MESSAGE ATHIS IS MESSAGE BINVALID COMMAND"

2. You should now verif y that the da ta area of the progr am is correct by typing:

R> m 002000..002030

You should see:

002000..00200f 54 48 49 53 20 49 53 20 4d 45 53 53 41 47 45 20

002030..002030 44

If this is not correc t, yo u can corr ect the er rors by re-en te ring only the modify m emo ry com ma nd s for th e part icul a r rows of memory that are wrong.

For example, if row 00200 0..0 0200 f shows these valu es:

002000..00200f 54 48 49 53 20 20 49 53 20 4d 45 53 53 41 47 45

you can correc t this ro w of mem ory by typing :

Or, you might ne e d to mod ify only one loca ti on, as i n the instance wher e address 00200f equals 22 hex rath er than 20 hex. Type:

R> m 00200f=22

3. Enter the progr am inform a ti on by typing t he following commands: (Note the hex lette rs mu st be pre c ed ed by a digit.)

R> m 001000..00100f=7a,07,00,0f,0f9,04,7a,01,00,0f, 0f8,00,0f8,00,6a,0a8 R> m 001010..00101f=00,0f,0f8,00,6a,2a,00,0f,0f8,00,0aa,00,47,0f6,0aa,41 R> m 001020..00102f=58,70,00,0a,0aa,42,58,70,00,10,58,00,00,18,0fb,11 R> m 001030..00103f=7a,04,00,00,20,00,58,00,00,14,0fb,11,7a,04,00,00 R> m 001040..00104f=20,11,58,00,00,08,0fb,0f,7a,04,00,00,20,22,7a,05 R> m 001050..00105f=00,0f,0f8,04,0fe,20,68,0d8,0b,05,1a,0e,46,0f8,7a,05 R> m 001060..00106f=00,0f,0f8,04,6c,4e,68,0de,0b,05,1a,0b,46,0f6,40,9c

Transferring Code

From A Host, HP

64700 In Transparent

Configuration

The method pro vided in this exa mp le assu mes th at you are runn ing an Assembler/ Linka ge Editor on an HP 9000/3 00 com put er running t he HP-UX operating syste m. In add ition , you must have the HP 64000 transfer soft war e runni ng on your host .

If you are not using a n Assem ble r/L i nka ge Edit or, you m ay be able to adapt the meth ods be lo w to lo ad your code in to the emulator (ref er to the HP 6470 0 User’s Referenc e manual for he lp).

If you are not able to transfer code fro m your host to the emulator usi ng one of these me tho ds, use t he me thod de sc ribed previo usly unde r "Transfe rri ng Co de From A Term ina l In Sta nda l one Mode ", as it will work in all cases. However, transf errin g co de using host tra nsfe r facilit ie s is e asi e r an d fa ste r th an mod ifying memory l ocations, especia lly for lar ge progr ams.

1. First, you must estab li sh co mmun ic ati ons wit h you r host computer through t he transpa re nt mode link prov ided i n the HP 64700. Type:

R> xp -s 02a

This sets the sec ond esc a pe cha ra cte r t o "*".(The first esc a pe character rema ins at the HP 64700 powe rup defau lt of hex 01b, which is the ASCII <ESC>cha ra cte r.) The sequen ce "<ESC>*" togg les the tran spa re nt mode softwa re within the HP 64700 for the dura tion of one comma nd (tha t is, any va li d line of HP 64700 commands (n ot exce ed 254 cha ract ers) concate na ted by sem icol ons a nd t er mi nate d by a <carr ia ge return>). Re fe r to t he User’s Refere nc e manual fo r more informa ti on on the xp c om ma nd .

Enable the tra nsparent mode l ink by typing :

R> xp -e

If you then press <RE T URN> a few time s, you should see :

This is the login prom pt for an HP- UX host syst em. (Your prompt may diff er dep ending on how your system manag er has configure d yo ur syst em. )

2. Log in to your host system and sta rt up an edi tor such as "vi". You should now enter th e sourc e code for the sam ple progr am shown at the beginnin g of the cha pt er . When fin ishe d, sa ve the program to file na m e "sam ppr og. src".

Note

If you need help lea rni ng ho w to log in to your HP-UX host syst e m or use other features of the system, such as editors, refer to the HP-UX Concepts and Tu tor ials gu ides a nd you r HP-UX system admi nistrator.

3. Assemble and link your code.

4. Convert your absol ute fi le gene ra ted above into HP format with the followin g co mm and. This is neede d to loa d the file into the emulator.

$ h83cnvhp -x sampprog

An HP format absolut e file sa mp prog .X will be genera ted .

Now it’s time to transf er your c ode into the emul ator. Do the following:

1. Disable the transp aren t mode so that your ter mina l will talk direct ly to the emulator. Type:

$ <ESC>* xp -d

The "<ESC>*" seque nc e temp orarily toggl e s the tra nsparent mode so that the emul a tor will acce pt com m an ds; "xp -d" then fully disables the transparent mode.

2. Load code into the emulator by typing:

R> load -hbo transfer -rtb sampprog.X<ESC>* (NOTE: DO NOT

TYPE CARRIAGE RETURN!)

The system will respond:

This is not what we we re exp ect ing to se e. (W e expec t ed to see the program executed Exe_Cmd routine which starts from 101e hex.) As you can see at the fist line of the trace list, address 101e hex appears on the address bu s duri ng th e program execut in g Sca n loop. This t rig ge re d the emulation ana l yzer before EXE_C md rout ine was exe c ut ed . T o avoid mis-trigg er by this cause , set the trigg er condit io n to the sec ond instructio n of the ro utine you wa nt to trace. Type:

Triggering the

Analyzer by Data

You may want to trigge r the em ula tion analyzer when spec i fic da ta appears on th e dat a bus. You can acc om pl ish t his wi th the followi ng command.

U> tg data=<data>

There are some points to be noticed when you trigger the analyzer in this way. You always need to specify the <data> with 16 bits value even when acc e ss to th e dat a is per form e d by by te acc e ss. This i s because the anal yz er is design ed so that it can capture data on interna l data bus (which has 16 bits width) . The following tabl e shows the way to speci fy the trigge r condition by data.

*1 dd means 8 bits data *2 hhll means 16 bits data

2-34 Getting Started

For example, to trig ger the ana lyze r when the pr ocesso r performs word access to data 1234 he x in 16 bit bus are a, you can spe c ify the following :

U> tg data=1234

To trigger the anal yzer when the proc e ssor ac ce sse s da ta 12 hex to the even address loc ate d in 8 bit data bus are a:

U> tg data=12xx

Page 55

On the other hand, to tri gge r 12 hex to the od d add ress loca te d 8 bit data bus.

U> tg data=0xx12

Notice that you always need to specify "xx" value to capture byte access to 8 bit data bus area. Be careful to trigger the analyzer by data.

You’re now finishe d wi th the "Get ting Sta rt e d" ex ampl e . You can procee d on with using t he emulat or a nd use this man ual and the Terminal Inte rfac e Reference manual as neede d to answer yo ur question s.

Caution

The following precautions sho uld be tak en while usi ng the H8/30 03 emula to r. Damage to the emulator circuitr y ma y re s ul t i f the se precauti ons a re not obse rve d.

Power Down Target Syste m. Turn off power to the user target syste m and to the H8/3003 e m ulat or be for e att a ch ing and deta ching the QFP adaptor to the emulator or target syste m to avoid circuit dama ge resulting from vo ltag e transients or mis-inse rt ion of the QFP board.

Verify User Plug Ori ent ation. Make certain that Pin 1 of the QFP socket/a da pto r and Pin 1 of the QFP ada pt or a re prop er ly aligned before inserting the QFP adapt or the QFP socke t/a da ptor. Failur e to do so may result in damage to the emulator circuitry.

Protect Against Static Discharge. The H8/3003 emulator and the QFP adaptor co ntai n devic e s whic h are suscep ti ble to dama ge by stat ic discharge . There for e, ope ra tors shou ld tak e prec aut ion ar y mea sure s befor e ha nd li ng the user pl ug t o av oid em ul at or damage .

Compatibility of VOLTAGE/CURRENCY. Please be sure to check that the voltage/curre ncy of the emulat or and targe t system bein g connecte d are co mpat ib le . If there is a disc re pa nc y, dam ag e ma y result .

Protect Targe t System CM O S Compone nts. If your target syste m includes any CMOS c omponents, turn on the targ et syste m fir st, then turn on the H8/30 03 e mu la to r; when po wer ing down, tur n off the emulato r fir st, then turn off power to the targe t syste m .

cf ba The ba (bus arbi trat ion ) co nfi gura t ion item defines how your em ula to r

responds to bus reque st signa ls from the target syste m.

M> cf ba=en

When bus arbitra t ion is enab led, the /B REQ (bus re que st) signal from the target system is responded to exactly as it would be if only the emulation proc esso r was pr ese nt without an emulat or. In othe r word s, if the emulation processor rec eive s a /BRE Q from th e tar get syst em, it will respond by asserting /BACK and will set the various proc e ssor lines to tri-sta te . /BREQ is t hen re lea sed by the targ et ; /BACK is negated by the proc e ssor, and th e em ulat ion proc e ssor re sta rt s execution.

M> cf ba=dis

When you disa ble bus arbitratio n by ente ri ng t he abo ve comm a nd, the emulator ignores the /B REQ signal from the target system. The emulation pr oc esso r wil l never dri ve the /B ACK line true; nor will it place the address, data and control signals i nto the tri-state mod e.

Enabling and disabling bus master arbitration can be useful to you in isolating targe t system pro blem s. For exampl e, you may have a situation where th e processo r ne ver seem s to exec ute any code . You can disable bus arbitration using cf ba=dis t o ch ec k a nd see if faul ty arbitrat ion circ uitry i n your targe t syst em is con tri but in g to the probl e m.

Note

Without a stack po inte r, the emul a tor is unabl e to make the tra nsit io n to the run state, ste p, or pe rfo rm many ot he r emu la tion functions. However, usin g this opt ion do es n ot preclude you from ch an gin g the stack point er val ue or loca t ion with in yo ur pro gra m ; it just set s the initia l co ndition s to a ll ow a ru n to begin.

cf tdma The tdma (trace intern al DMA c ycles) con figuration item defines

whether or not the emulator traces internal DMA cycles.

M> cf tdma=en

When you ena ble this item with the above co mm and, each tim e DMA perfo rm ed, one em ula t ion analyz er state will be ge nerated to recog niz e the DMA cycle.

M> cf tdma=dis

When disa bl e d, no an al yz e r sta te wil l be ge ne rated at the occ ur re nce of DMA. Therefore, any DMA cycle will be ignored by the analyzer.

Note

Internal DMA cyc le s may be trace d rega rdl e ss of this co nfi guration in order to disassem ble the trac e list corre ctly .

cf trfsh The trfsh (tra ce ref re sh cy cl e s) co nfi gura t ion item de fin es whe t he r or

not the emulator traces refresh cycles.

M> cf trfsh=en

When you ena bl e t his ite m with the ab ove co mm and, refresh c yc le s a re trace d by t he em ul at ion analyzer.

M> cf trfsh=dis

When disabled, ref re sh cy cl e s are not trac e d by th e ana lyzer.

Refresh c yc les m ay be tra ce d regardless of th is c onfi guration in orde r to disas s emble the trace list correctly.

Note

Executing this command will drive the emulator into the reset state.

cf trst The trst (target rese t ) configuration item allows you to speci fy whe ther

or not the emulator respon ds to /RE S and /STBY sign als from th e target system duri ng fo re grou nd ope ra tion. When running the background monitor, the emulator ignores such signals.

M> cf trst=en

When you enabl e targe t system rese t with the abov e com m and, the emulator wil l respon d to /RE S inpu t during fore gro und op er atio n.

M> cf trst=dis

When disabl e d, the em ul a tor won’t resp ond t o /RE S a nd /ST BY i nput s from the target system.

/RES and /STB Y signals are alwa ys ig nore d du rin g ba ck grou nd operat ion reg ar dle ss of t his c onf iguration.

Memory Mapping Before you begin an emulat or session , you mu st spec ify the loca tion

and type of various me mory reg ion s used by your progr ams a nd your target system (wheth er or not it exists). You do this for se ve ral rea sons:

the emula t or m ust kn ow whe ther a given mem ory l oc at io n resides in emulati on memor y or in target syste m memo ry. This allows the emula to r to prope rl y orien t buf fers for t he given data transfer.

the emula t or needs to kn ow the siz e of any e mu la ti on m e mo ry blocks so it can pro pe rly rese rv e em ula t ion memory spac e for those blocks.

the emulat or m ust kn ow if a giv en space is RAM (re ad/ write), ROM (read only), or do esn ’t exist. This all ows the e mula to r to determine if certain acti ons tak en by the emulation pr oc esso r are proper fo r the m em or y typ e be ing a cc e ss e d. For ex am pl e , if the processor t rie s to write to a em ula tion memory loc atio n mapped as ROM, the em ulat or wil l not permit the write (eve n if the memory at the given location is actually RAM). (You can optionally configure the emulator to break to the monitor upon such occu rre nce with the bc -e rom command.) Also, if the emulation processor att empt s to ac cess a non exist e nt location (known as "gua rd ed "), the emul a tor will bre ak to the monitor .

You use the map command to define me mo ry ra nge s a nd types for th e emulator. The H8/ 3003 emulat or memo ry map per allo ws you to define up to 16 diffe re nt map term s; each map t er m ha s a mi nim um siz e of 512 byte s. If you specify a val ue le ss tha n 512 byte, th e em ulator wil l automatically allocate an entire block. You can specify one of five differe nt memory types (erom, eram, trom, tram, grd).

For example, you mig ht be deve loping a system with the following characte rist ic s:

input port at 0f000 hex
