ROM Address Register
The following registers are used to address the ROM.
• Page address register (PA) :
Holds ROM`s page number (0~Fh) to be addressed.
• Page buffer register (PB) :
Value of PB is loaded by an LPBI command when newly addressing a page.
Then it is shifted into the PA when rightly executing a branch instruction (BR)
and a subroutine call (CAL).
• Program counter (PC) :
Available for addressing word on each page.
• Stack register (SR) :
Stores returned-word address in the subroutine call mode.
(1) Page address register and page buffer register :
Address one of pages #0 to #15 in the ROM by the 4-bit binary counter.
Unlike the program counter, the page address register is usually unchanged
so that the program will repeat on the same page unless a page changing
command is issued. To change the page address, take two steps such as
(1) writing in the page buffer what page to jump to (execution of LPBI) and
(2) execution of BR or CAL, because and instruction code is of eight bits so
that page and word cannot be specified at the same time.
In case a return instruction (RTN) is executed within the subroutine that has
been called in the other page, the page address will be changed at the
same time.
(2) Program counter :
This 6-bit binary counter increments for each fetch to address a word in the
currently addressed page having an instruction to be next executed.
For easier programming, at turning on the power, the program counter is
¡ È ¡ È
. Then the program
reset to the zero location. The PA is also set to
0
counter specifies the next ROM address in random sequence.
When BR, CAL or RTN instructions are decoded, the switches on each step
are turned off not to update the address. Then, for BR or CAL, address
data are taken in from the instruction operands (a0 to a5), or for RTN, and
address is fetched from stack register No. 1.
(3) Stack register :
This stack register provides two stages each for the program counter (6
bits) and the page address register (4bits) so that subroutine nesting can be
mode on two levels.

The whole data memory area is indirectly specified by a data pointer (X,Y). Page
number is specified by zero bit of X register, and words in the page by 4 bits in

Y-register (Y)
Y-register has 4 bits. It operates as a data pointer or a general-purpose register.
Y-register specifies and address (a0~a3) in a page of data memory, as well as it
is used to specify an output port. Further it is used to specify a mode of carrier
signal outputted from the REMOUT port. It can also be treated as a general-
purpose register on a program.
Accumulator (ACC
)
The 4-bit register for holding data and calculation results.
Arithmetic and Logic Unit (ALU)
In this unit, 4bits of adder/comparator are connected in parallel as it`s main
components and they are combined with status latch and status logic (flag.)
(1) Operation circuit (ALU) :
The adder/comparator serves fundamentally for full addition and data
comparison. It executes subtraction by making a complement by processing
an inversed output of ACC (ACC+1)
(2) Status logic :
This is to bring an ST, or flag to control the flow of a program. It occurs when
a specified instruction is executed in two cases such as overflow in operation
and two inputs unequal.

State Counter (SC)
A fundamental machine cycle timing chart is shown below. Every instruction is
one byte length. Its execution time is the same. Execution of one instruction
takes 6 clocks for fetch cycle and 6 clocks for execute cycle (12 clocks in total).
Virtually these two cycles proceed simultaneously, and thus it is apparently
completed in 6 clocks (one machine cycle). Exceptionally BR, CAL and RTN
instructions is normal execution time since they change an addressing
sequencially. Therefore, the next instruction is prefetched so that its execution
is completed within the fetch cycle.

<Purpose>
For some programs, normal sequential program execution can
be change.
A branch is conditionally implemented depending on the status
of results obtained by executing the previous instruction.
<Comment>
• Branch instruction is always conditional depending on the
status.
a. If the status is reset (logic 0), a branch instruction is not
rightly executed but the next instruction of the sequence is
executed.
b. If the status is set (logic 1), a branch instruction is executed
as follows.
• Branch is available in two types - short and long. The former
is for addressing in the current page and the latter for
addressing in the other page. Which type of branch to exeute
is decided according to the PB register. To execute a long
branch, data of the PB register should in advance be modified
to a desired page address through the LPBI instruction.

<Comment>
• In a program, control is allowed to be transferred to a mutual
subroutine. Since a call instruction preserves the return
address, it is possible to call the subroutine from different
locations in a program, and the subroutine can return control
accurately to the address that is preserved by the use of the
call return instruction (RTN).
Such calling is always conditional depending on the status.
a. If the status is reset, call is not executed.
b. If the status is set, call is rightly executed.
The subroutine stack (SR) of three levels enables a subroutine
to be manipulated on three levels. Besides, a long call (to call
another page) can be executed on any level.
• For a long call, an LPBI instruction should be executed before
the CAL. When LPBI is omitted (and when PA=PB), a short
call (calling in the same page) is executed.

Caution on Operation
• It is required to install a 24DIP IC socket in the application system. The
connection cable is connected to the socket.
• There is a possibility that the ceramic oscillator on the application system cannot
oscillate properly due to the influence of connection cable wiring capacitor or other
reasons. In such a case, install the oscillator on the evaluation board.
• Since the GMS 30000 EVA is designed to evaluate the program operations, there
is a case where the AC and DC characteristics differ from those of the mass-
produced chips

1. Overview
The simulator is a program for GMS300 Series 4-bit one-chip microcomputer.
The environment is organized based upon Hexa file of *.RHX and Cross Reference file
of *.CRF generated by assembling the source program coded by programmer.

2. Characteristics of Simulator
- User-friendly pop-up window menu. Select the necessary command and display
the screen in windows format so that users can know the execution results.
- Display always the register window in the right side so that programmer can check
easily the change of data memory value as program proceeds.
- Maintain the previous simulator environment if user does not make the extra changes
when re-executing after logging out completely from the simulator
previously executed by loading the source program. In other words, the previously-
executed file is automatically loaded when the simulator is executed (GMS30K.GSP
file).
- When trace command ([F8] or > T command) is executed, the changed values are
noticed easily by displaying the highlighted changed values in register and memory
windows, if the contents of each register or data memory is changed as command
line is processed.
- When trace command ([F8] or > T command) is executed, the current execution
line is highlighted.
- Out of the simulator commands, load or save commands is executable in pop-up
windows. In-line command is executable as prompt command in the command
window.

3. Screen Organization of Simulator
Screen is basically organized with four windows; Memory, Source, Command and
Register. Source and Command windows can be enlarged up to the full screen
size (CTRL-[F10]). Movement between windows is made by [F6].
3.1 Memory Window
Data memory contents of the currently selected micom is displayed. 32 nibble
data values of 00~1F(h) addresses are displayed.
3.2 Source Window
The contents of *.RHX file called by load command is displayed in the state of
being disassembled. Addresses are displayed randomly in the state of
polynomial together with instruction code and mnemonic. If *.CRF file is
called, label is displayed at the corresponding position. Display position of
source program is adjustable with Up/Down arrow keys and Page Up/Down
keys.
3.3 Command Window
All kinds of commands provided by simulator is executed by In-line command,
and the execution results of the commands are displayed. Command window
size is adjustable with [CTRL]-[F10].

register value after the previous command before the current program counter
is executed is displayed. All kinds of register and I/O ports displayed in
register window are as follows.

5.1 File Load
Use one of three ways to load the file to run from the simulator. First execute
the GSSIM.EXE file from DOS and name it as a parameter.
>a:\GSSIM TEST.RHX (Here the extention needs not be input.)
The following screen will be displayed.
5 - 10
Chapter 5. Software
Second, execute the GSSIM.EXE file and then the Load RHX (Hot key is
[F2]). The following small window is open at the center of screen waiting for
user to input the Hexa filename to work.
*
File Name
*
A : \UNNAMED.RHX
When no file is selected, Unnamed.rhx filename is displayed. When the
filename to work is input immediately, the file from the current directory is
called. If the specific directory is assigned, the file from the assigned directory
is called.
Third, call the file to work through using the >LP [filename] from command
window by in-line command.
Here for example, load the TEST.RHX file
*
File Name
*
A : \TEST.RHX
TEST.RHX file is called and the contents of HEXA file is analyzed from the
simulator. The source contents in the state of being disassembled is
displayed from Source window. Incase of filename input, although RHX is not
input, .RHX extension presumed to include by default.

5.2 File Store
When the specific part of source program is changed under the simulator
environment by calling the working file, the corresponding Hexa file needs to
be stored. Use one of the following two methods.
First, when executing the pop-up command Save RHX (Hot key is [F3]), the
following small window is open at the center of screen waiting for user to input
the Hexa filename. The filename called by file load command by default is
displayed. When the filename is not changed, hit just the [Enter] key. When
user wants to change the filename to store, input the filename to change.
*
File Name
*
A : \TEST.RHX
Second, store the processed Hexa file using > WP [filename] from command
window with In-line command.
Here when the same filename to store already exists in the disk, File
Already Exist message comes up asking user by [YES/NO] if user overwrite
or not.
