Architecture CHAPTER 2. Architecture 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. Program capacity (pages) 01 8 23 45 67 Page 0 Page 1 Page 2 Page 15 63 0 A0~A5 Program counter (PC) 6 Stack 1 2 15 A6~A9 Page address register (PA) 4 register (Level E1E) (Level E2E) Page buffer (PB) (SR) (PRS) (Level E3E) Fig 2-1 Configuration of Program Memory 2- 1 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 E0E. 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. 2- 2 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.

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. 2- 4 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.

Architecture Clock Generator The GMS340 series has an internal clock oscillator. The oscillator circuit is designed to operate with an external ceramic resonator. Internal capacitors are available as a masked option. Oscillator circuit is able to organize by connecting ceramic resonator to outside. (In order to built in capacitor for oscillation as masked option.) * It is necessary to connect capacitor to outside in order to change ceramic resonator, You must examine refer to a manufacturers OSC1 OSC2 OSC1 23 OSC2 22 23 C1 22 C2 Operating Frequency fOSC = 2.4 ~ 4MHz Internal capacitor option fOSC = 300 ~ 500KHz No Internal capacitor option Oscillation Circuit Circuit 1 Circuit 2 Circuit 1 2- 6 Chapter 2. Architecture Pulse generator The following frequency and duty ratio are selected for carrier signal outputted from the REMOUT port depending on a PMR (Pulse Mode Register) value set in a program. T T1 PMR 0 1 2 3 4 5 6 REMOUT signal T=1/fPUL = 12/fOSC [96/fOSC], T=1/fPUL = 12/fOSC [96/fOSC], T=1/fPUL = 8/fOSC [64/fOSC], T=1/fPUL = 8/fOSC [64/fOSC], T=1/fPUL = 11/fOSC [88/fOSC], No Pulse (same to D0~D9) T=1/fPUL = 12/fOSC [96/fOSC], T1/T = 1/4 T1/T = 1/2 T1/T = 1/3 T1/T = 1/2 T1/T = 1/4 T1/T = 4/11 * Default value is E0E * [ ] means the value of ETE, when Instruction cycle is fOSC/48 Table 2-2 PMR selection table 2- 7 Chapter 2. Architecture Initial Reset Circuit RESET pin must be down to ELE more than 4 machine cycle by outside capacitor or other for power on reset. The mean of 1 machine cycle is below. 1 machine cycle is 6/fOSC, however, operating voltage must be in recommended operating conditions, and clock oscillating stability. * It is required to adjust C value depending on rising time of power supply. (Example shows the case of rising time shorter than 10ms.) 1 RESET 0.1uF 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 62 13/fOSC (108.026ms at fOSC=455KHz.) 86213/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>) fOSC/6 or fOSC/48 Binary counter (14 steps) RESET (edge-trigger) CPU reset Reset by instruction REMOUT output Mask Option 2- 8 Chapter 2. Architecture 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 ELE. 3. Part other than WDT, D8~D9 output and REMOUT output have a value before come into stop mode. EBut, the state of D0~D7 output in stop mode is able to choose as masked option. ELE 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 ELE. 1. State of D0~D7 output and REMOUT output is return to state of before stop mode is achieved. 2. After 10248 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 ELE, 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).

Load Memory from Accumulator Set I M(X,Y) c A Data of four bits from the accumulator is stored in the RAM location addressed by the X-register and Y-register. Such data is left unchanged. (5) LMAIY Naming : Status : Format : Function : Load Memory from Accumulator and Increment Y-Register Set I M(X,Y) c A, Y c Y+1 Data of four bits from the accumulator is stored in the RAM location addressed by the X-register and Y-register. Such data is left unchanged. 3- 6 Chapter 3. Instruction (6) LYM Naming : Status : Format : Function : Load Y-Register form Memory Set I Y c M(X,Y) Data from the RAM location addressed by the X-register and Y-register is loaded into the Y-register. Data in the memory is left unchanged. (7) LAM Naming : Status : Format : Function : Load Accumulator from Memory Set I A c M(X,Y) Data from the RAM location addressed by the X-register and Y-register is loaded into the Y-register. Data in the memory is left unchanged. (8) XMA Naming : Status : Format : Function : Exchanged Memory and Accumulator Set I M(X,Y) e A Data from the memory addressed by X-register and Y-register is exchanged with data from the accumulator. For example, this instruction is useful to fetch a memory word into the accumulator for operation and store current data from the accumulator into the RAM. The accumulator can be restored by another XMA instruction. (9) LYI i Naming : Status : Format : Operand : Function : Load Y-Register from Immediate Set Constant 0 A i A 15 Y c i To load a constant in Y-register. It is typically used to specify Y-register in a particular RAM word address, to specify the address of a selected output line, to set Y-register for specifying a carrier signal outputted from OUT port, and to initialize Y-register for loop control. The accumulator can be restored by another XMA instruction. Data of four bits from operand of instruction is transferred to the Y-register. 3- 7 Chapter 3. Instruction (10) LMIIY i Naming : Status : Format : Operand : Function : Load Memory from Immediate and Increment Y-Register Set Constant 0 A i A 15 M(X,Y) c i, Y c Y + 1 Data of four bits from operand of instruction is stored into the RAM location addressed by the X-register and Y-register. Then data in the Y-register is incremented by one. (11) LXI n Naming : Status : Format : Operand : Function : Load X-Register from Immediate Set X file address 0 A n A 3 X c n A constant is loaded in X-register. It is used to set X-register in an index of desired RAM page. Operand of 1 bit of command is loaded in X-register. (12) SEM n Naming : Status : Format : Operand : Function : Set Memory Bit Set Bit address 0 A n A 3 M(X,Y,n) c 1 Depending on the selection in operand of operand, one of four bits is set as logic 1 in the RAM memory addressed in accordance with the data of the X-register and Y-register. (13) REM n Naming : Status : Format : Operand : Function : Reset Memory Bit Set Bit address 0 A n A 3 M(X,Y,n) c 0 Depending on the selection in operand of operand, one of four bits is set as logic 0 in the RAM memory addressed in accordance with the data of the X-register and Y-register. 3- 8 Chapter 3. Instruction (14) TM n Naming : Status : Format : Operand : Function : Test Memory Bit Comparison results to status Bit address 0 A n A 3 M(X,Y,n) c 1?

(15) BR a Naming : Status : Format : Operand : Function : Branch on status 1 Conditional depending on the status Branch address a (Addr) When ST =1 , PA c PB, PC c a(Addr) When ST = 0, PC c PC + 1, ST c 1 Note : PC indicates the next address in a fixed sequence that is actually pseudo-random count. 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. 3- 9 Chapter 3. Instruction (16) CAL a Naming : Status : Format : Operand : Function : Subroutine Call on status 1 Conditional depending on the status Subroutine code address a(Addr) When ST =1 , PC c a(Addr) PA c PB c PC + 1, SR1 PSR1 c PA c SR1 SR2 PSR2 c PSR1 c SR2 SR3 PSR3 c PSR2 c PC + 1 When ST = 0 PC PB c PS ST c 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. 3 - 10 Chapter 3. Instruction (17) RTN Naming : Status : Format : Function : Return from Subroutine Set PC c SR1 PA, PB c PSR1 c SR2 SR1 PSR1 c PSR2 c SR3 SR2 PSR2 c PSR3 c SR3 SR3 PSR3 c PSR2 c 1 ST Control is returned from the called subroutine to the calling program. Control is returned to its home routine by transferring to the PC the data of the return address that has been saved in the stack register (SR1). At the same time, data of the page stack register (PSR1) is transferred to the PA and PB. (18) LPBI i Naming : Status : Format : Operand : Function : Load Page Buffer Register from Immediate Set ROM page address 0 A i A 15 PB c i A new ROM page address is loaded into the page buffer register (PB). This loading is necessary for a long branch or call instruction. The PB register is loaded together with three bits from 4 bit operand. (19) AM Naming : Status : Format : Function : Add Accumulator to Memory and Status 1 on Carry Carry to status A c M(X,Y)+A, ST c 1(when total>15), ST c 0 (when total A15) Data in the memory location addressed by the X and Y-register is added to data of the accumulator.

Data in the memory is not changed. 3 - 11 Chapter 3. Instruction (20) SM Naming : Status : Format : Function : Subtract Accumulator to Memory and Status 1 Not Borrow Carry to status A c M(X,Y) - A ST c 1(when A A M(X,Y)) ST c 0(when A > M(X,Y)) Data of the accumulator is, through a 2s complemental addition, subtracted from the memory word addressed by the Y-register. Results are stored in the accumulator. If data of the accumulator is less than or equal to the memory word, the status is set to indicate that a borrow is not caused. If more than the memory word, a borrow occurs to reset the status to E0E. (21) IM Naming : Status : Format : Function : Increment Memory and Status 1 on Carry Carry to status A c M(X,Y) + 1 ST c 1(when M(X,Y) A 15) ST c 0(when M(X,Y) < 15) (22) DM Naming : Status : Format : Function : Decrement Memory and Status 1 on Not Borrow Carry to status A c M(X,Y) - 1 ST c 1(when M(X,Y) A1) ST c 0 (when M(X,Y) = 0) Data of the memory addressed by the X and Y-register is fetched, and one is subtracted from this word (addition of Fh)> Results are stored in the accumulator. Carry data as results is transferred to the status. If the data is more than or equal to one, the status is set to indicate that no borrow is caused. The memory is left unchanged. 3 - 12 Chapter 3. Instruction (23) IA Naming : Status : Format : Function : Increment Accumulator Set A c A+1 Data of the accumulator is incremented by one. Results are returned to the accumulator. A carry is not allowed to have effect upon the status. (24) IY Naming : Status : Format : Function : Increment Y-Register and Status 1 on Carry Carry to status Y c Y + 1 ST c 1 (when Y = 15) ST c 0 (when Y < 15) Data of the Y-register is incremented by one and results are returned to the Y-register. Carry data as results is transferred to the status. When the total is more than 15, the status is set. (25) DA Naming : Status : Format : Function : Decrement Accumulator and Status 1 on Borrow Carry to status A c A - 1 ST c 1(when A A1) ST c 0 (when A = 0) Data of the accumulator is decremented by one. As a result (by addition of Fh), if a borrow is caused, the status is reset to E0E by logic. If the data is more than one, no borrow occurs and thus the status is set to E1E. 3 - 13 Chapter 3. Instruction (29) ALEM Naming : Status : Format : Function : Accumulator Less Equal Memory Carry to status A A M(X,Y) ST c 1 (when A A M(X,Y)) ST c 0 (when A > M(X,Y)) Data of the accumulator is, through a complemental addition, subtracted from data in the memory location addressed by the X and Y-register. Carry data obtained is transferred to the status. When the status is E1E, it indicates that the data of the accumulator is less than or equal to the data of the memory word. Neither of those data is not changed. (30) ALEI Naming : Status : Format : Function : Accumulator Less Equal Immediate Carry to status A A i ST c 1 (when A A i) ST c 0 (when A > i) (31) MNEZ Naming : Status : Format : Function : Memory Not Equal Zero Comparison results to status M(X,Y) A 0 ST c 1(when M(X,Y) A 0) ST c 0 (when M(X,Y) = 0) A memory word is compared with zero.
