Chapter 1. Introduction Masked options The GMS300 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). 5. Output form at stop mode D0~D7 : ILI or keep before stop mode
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 ILI. 3. Part other than WDT, D8~D9 output and REMOUT output have a value before come into stop mode.
IBut, the state of D0~D7 output in stop mode is able to choose as masked option. ILI 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 ILI. 1. State of D0~D7 output and REMOUT output is return to state of before stop mode is achieved. 2. After 1024O8 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 ILI, stop instruction is same to NOP instruction.

BLOCK DESCRIPTION
Characteristics The GMS300 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.

Chapter 2. Architecture ROM Address Register The following registers are used to address the ROM. * Page address register (PA) : Holds ROMs 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 I0I. 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.

Chapter 2. Architecture 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.

Chapter 2. Architecture 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 its 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.
I/O circuit Ports K0~K3 are 4-bit input ports were pulled up by MOS Tr resistor internally. Ports D0~D9 are output ports, each of which can be independently set and reset. The output is in the form of Nch-open-drain circuit. The input is in the form of a MOS transistor input (MOS Tr resistor pull-up. Masked option). Further, the REMOUT port is a large current driven output port. This port is designed for source current to drive a high current device.

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 counter of 14 steps. The selected of fOSC/6 cycle come in the first step of WDT. If this counter was overflowed, come out reset signal automatically, internal circuit is initialized. The overflow time is 6O213/fOSC (108.026ms at fOSC = 455KHz). 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 1-13 STOP function>)

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.

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.

Configuration of Simulator 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.
Execution Environment System : IBM-PC/AT or higher (MS-DOS or PC-DOS) Video : Hercules, EGA or VGA color
Organizing files
GSSIM.EXE GMS30K.GSP : : Simulator execution file Store the simulator environment. It is generated automatically when executing the program initially (Selected CPU. Store the file names previously loaded.). Help file of simulator commands. Record the working history of users. Generated by LOG ON and LOG OFF commands. List a set of simulator command. Generated by user. Provide the port input-value when executing the simulator. Generated by user.

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.
