Chapter 2. Architecture
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
reset to the zero location. The PA is also set to ¡È0¡È. Then the program
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.

Data memory (RAM)
Up to 32 nibbles (16 words ¡¿ 2pages ¡¿ 4bits) is incorporated for storing data.
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. Data memory is composed in 16 nibbles/page. Figure 2.2 shows the
configuration.

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 generalpurpose 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.

Chapter 2. Architecture
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.

Watch Dog Timer (WDT)
Watch dog timer is organized binary of 14 steps. By the selected oscillation
option, the signal of fOSC/6 cycle comes in the first step of WDT. If this counter
was overflowed, come out reset signal automatically, internal circuit is initialized.
The overflow time is 6¡¿2 13/fOSC (108.026ms at fOSC=455KHz.)
8¡¿6¡¿213/fOSC (108.026ms at fOSC = 3.64MHz)
Normally, the binary counter must be reset before the overflow by using reset
instruction (WDTR) or / and REMOUT port (Y-reg=8, So instruction execution) at
masked option.
* It is constantly reset in STOP mode. When STOP is released, counting is
restarted. (Refer to 2-10 STOP function>)

STOP Function
Stop mode can be achieved by STOP instructions.
In stop mode :
1. Oscillator is stopped, the operating current is low.
2. Watch dog timer is reset, D8~D9 output and REMOUT output are ¡ÈL¡È.
3. Part other than WDT, D8~D9 output and REMOUT output have a value before
come into stop mode.
¡ÈBut, the state of D0~D7 output in stop mode is able to choose as masked
option. ¡ÈL¡È output or same level before come into stop mode.
The function to release stop mode is able to choose each bit of K or R input.
Stop mode is released when one of K or R input is going to ¡ÈL¡È.
1. State of D0~D7 output and REMOUT output is return to state of before stop mode
is achieved.
2. After 1024¡¿8 enable clocks for stable oscillating. First instruction start to operate.
3. In return to normal operation, WDT is counted from zero again.
But, at executing stop instruction, if one of K or R input is chosen to ¡ÈL¡È, stop
instruction is same to NOP instruction.
Masked options
The GMS340 series offer the following optional features.
These options are masked.
1. Watch dog timer reset by REMOUT output signal.
2. Input terminals having STOP release mode : K0~K3, R0~R3.
3. I/O terminals having pull-up resistor : R0~R3
4. Ceramic oscillation circuit contained (or not contained).
[This option is not available for MHz Ceramic oscillator]

A branch is conditionally implemented depending on the status
of results obtained by executing the previous instruction.
• 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.

• 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 massproduced 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 previouslyexecuted 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.

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].

2) ã
3) _
Indicates insertion of space characters.
4) In
Indicates range.
5) [ ]
Indicates it is omittable.
6) No. used on this system are hexadecimal. However, the machine cycles are
decimal.
(Common items on this simulator)
1) This simulator accepts up to 132 characters per each line.
Before pressing `ã` key, data can be modified in the following procedure.
<BS> Key deletes one character and the cursor sets back by one character.
2) Commands can be input both in block and small letters and both are treated
as the same.
3) Commands can be terminated by inputting `.`.
4) Command history (recall)
This simulator has 16 command buffers and each time `Control A` is
pressed, command immediately before the current one is displayed.
5) When `!XX` is executed to `*`, MS-DOS* commands can be executed
temporarily.
6) Regarding the omission indicated with [ ], when one [<address>] or [In] is
omitted, the area may not be recognized. In this case, be careful as the
current operation cannot be ensured.
7) When `.XXXX` is specified, it is treated as a symbol. Therefore, before using
this specification, specification of Symbol file should have been made.
8) When `ESC` key is pressed, command execution is stopped and the system
moves to `*` mode.
9) When In is LXX< XX indicates No. of words and when there is no L, XX
indicates an address.
10) For command separator (indicated with_in this Manual), `_` or `,` can be
used.
11) When `Control C` is pressed, the system goes back to `MS-DOS*`.
12) In case of both sequential and polynomial address, the first two digits of an
<address> indicate No. of page and the latter two digits indicate the address.
Hereunder is the explanation on each command used on this system.
