BLOCK DESCRIPTION

Characteristics

The GMS340 series can incorporate maximum 1024 words (64 words ¡¿ 16 pages ¡¿ 8bits) for program memory. Program counter PC (A0~A5) and page address register (A6~A9) are used to address the whole area of program memory having an instruction (8bits) to be next executed. The program memory consists of 64 words on each page, and thus each page can hold up to 64 steps of instructions. The program memory is composed as shown below.

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 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.

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.

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]

Operand : Branch address a (Addr) Function : When ST =1 , PA ¡ç PB, PC ¡ç a(Addr)

When ST = 0, PC ¡ç PC + 1, ST ¡ç 1 Note : PC indicates the next address in a fixed sequence that is actually pseudo-random count.

<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.

• 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.

SR3 ¡ç SR2 PSR3 ¡ç PSR2 When ST = 0 PC ¡ç PC + 1 PB ¡ç PS ST ¡ç 1 Note : PC actually has pseudo-random count against the next 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.

Configu r at io n of Sim ulator

1. Overvi ew

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.

Execution Environment

System : IBM-PC/AT or higher (MS-DOS or PC-DOS) Video : Hercules, EGA or VGA color

Organizing files

GSSIM.EXE : Simulator execution file GMS30K.GSP : Store the simulator environment. It is

generated automatically when executing the program initially (Selected CPU.

Store the file names previously loaded.). GMS30K.HLP : Help file of simulator commands. GMS30K.LOG : Record the working history of users. Generated

by LOG ON and LOG OFF commands. *.BAT : List a set of simulator command. Generated by

user. PORTIN.DAT : Provide the port input-value when executing

the simulator. Generated by user.

Supporting CPU

GMS30004, GMS30012, GMS30112, GMS30120, GMS30140

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.

6.3 Description of Commands

The symbols used in this chapter are defined as in below.

1) XXXX Indicates input from the keyboard.

Indicates Return key.

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.

A (Assemble)

[Function]

To assemble commands for each line from the specified <address> and write them in the memory.

[Format]

> A_ [<address>]

[Explanation]

With this, the system assembles commands for each line from the specified <address> and writes them in the memory. When <address> is omitted, data is written from the current `PC` address. Assemble can be finished by keying in `.`. When `_` is keyed in, the system goes back the address just before the current one.

[e.g.]

>A 200

0200 40 LYI 0

0201 21 LAM

BPI

BPO

[Explanation]

This command is used to the break point. Break on this simulator is to stop after executing the command on the specified address. When `BPS st` is specified, the system stops when the value on the machine cycle register becomes equal to st. When `BPI` is specified, the system stops before command execution every time command input is made. Unassemble displayed in this case is the address with input command. When `BPO` is specified, the system displays the value on that occasion on CRT and stops every time output command is made. When `BP` only or `BL` is specified, the state of the currently set break point is displayed. It is possible to used symbols for specifying adr. When `n` is omitted in break setting command, No. shall be allocated from 1 to all empty No.

U_[<address>] [_<In>]

[Explanation]

With this, the system unassembles the area specified with <In> from the specified <address> and displays in mnemonic. When [<address>] [<In>] are omitted, unassembling is performed from the

address immediately after the display start address.

Default value for <In> is 16. However, [<address>] cannot be omitted separately.

[e.g]

>U 200 L4

0200 40 LYI 00 0201 21 LAM 0203 77 ALEI 0E 0207 AF BR 2F >
