(4) Explanation of machine cycle field S shows the number of machine cycles required when skip is performed by an instruction with skip. The value of S changes as follows: * No skip ....................................................................................................................................................................... S = 0 * When instruction to be skipped is 1-byte or 2-byte instruction ......................................................................... S = 1 * When instruction to be skipped is 3-byte instruction (BR !addr, CALL !addr instruction) ............................. S = 2 Caution One machine cycle is required to skip a GETI instruction. One machine cycle is equivalent to one cycle (= tCY) of the CPU clock . Three times can be selected by PCC setting. 37 PD75312B, 75316B Mnemonic Machine Cycles Note 1 Bytes Operand Operation A n4 reg1 n4 XA n8 HL n8 rp2 n8 A (HL) A (rpa1) XA (HL) (HL) A (HL) XA A (mem) XA (mem) (mem) A (mem) XA A reg XA rp reg1 A rp1 XA A (HL) A (rpa1) XA (HL) A (mem) XA (mem) A reg1 XA rp XA (PC13-8 + DE)ROM XA (PC13-8 + XA)ROM A A + n4 A A + (HL) A, CY A + (HL) + CY A A - (HL) A, CY A - (HL) - CY A A n4 A A (HL) A A n4 A A (HL) A A n4 A A (HL) Addressing Area Skip Condition Stack A A, #n4 reg1, #n4 XA, #n8 HL, #n8 rp2, #n8 A, @HL A, @rpa1 XA, @HL MOV @HL, A @HL, XA A, mem Transfer XA, mem mem, A mem, XA A, reg XA, rp reg1, A rp1, XA A, @HL A, @rpa1 XA, @HL XCH A, mem XA, mem A,reg1 XA, rp Note 2 XA, @PCDE MOVT XA, @PCXA A, #n4 ADDS A, @HL ADDC SUBS Operation SUBC AND A, @HL A, @HL A, @HL A, #n4 A, @HL OR A, #n4 A, @HL XOR A, #n4 A, @HL 1 2 2 2 2 1 1 2 1 2 2 2 2 2 2 2 2 2 1 1 2 2 2 1 2 1 1 1 1 1 1 1 2 1 2 1 2 1 1 2 2 2 2 1 1 2 1 2 2 2 2 2 2 2 2 2 1 1 2 2 2 1 2 3 3 1+S 1+S 1 1+S 1 2 1 2 1 2 1 Stack A Stack B *1 *2 *1 *1 *1 *3 *3 *3 *3 *1 *2 *1 *3 *3 carry *1 *1 *1 *1 borrow carry *1 *1 *1 Notes 1.

When the oscillator frequency is 4.19 MHz < fXX 5.0 MHz, do not select PPC = 0011 as instruction execution time. If PCC = 0011 is selected, 1 machine cycle becomes less than 0.95 s, with the result that specified MIN. value 0.95 s cannot be observed. 3.

Do not connect it to the power supply pattern in which high current flows. * Do not fetch a signal from the oscillator. When the subsystem clock is used, special care is needed for the wiring. The subsystem clock oscillator is designed to be low-amplification circuit for low current consumption, thus mulfunction due to noise occurs more often than with the main system clock oscillator. 45 PD75312B, 75316B RECOMMENDED OSCILLATOR CONSTANTS MAIN SYSTEM CLOCK: CERAMIC RESONATOR (Ta = -40 to +85 C) Recommended constants Manufacture Product Name CSB x x x x J CSAx. x x xMK040 CSA x. x x MG040 CST x. x x MG040 CSA x. x x MG CST x. x x MGW 2.450 to 5.000 Internal Internal 1.800 to 2.440 Internal 30 Internal 30 - Frequency (MHz) C1 (pF) MURATA 1.000 to 1.250 1.251 to 1.799 100 100 C2 (pF) R (k) 5.6 Oscillator voltage range (V) MIN.

The most up-to-date documents should be used for design work. 75 PD75312B, 75316B NOTES FOR CMOS DEVICES 1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pulldown circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function. 76 PD75312B, 75316B The related documents indicated in this publication may include preliminary versions.
