SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER for VOLTAGE SYNTHESIZER

and ON-SCREEN DISPLAY CONTROLLER

ADDRESSING MODE

The memory access is reinforced with 17 kinds of addressing modes.

Refer to SERIES 740 <Software> User’s Manual for details.

MACHINE INSTRUCTIONS

There are 71 machine instructions. Refer to SERIES 740 <Soft- ware>

User’s Manual for details.

PROGRAMMING NOTES

(1) The divide ratio of the timer is 1/(n+1).

(2) Even though the BBC and BBS instructions are executed imme-

diately after the interrupt request bits are modified (by the pro-

gram), those instructions are only valid for the contents before

the modification. At least one instruction cycle is needed (such as

an NOP) between the modification of the interrupt request bits

and the execution of the BBC and BBS instructions.

(3) After the ADC and SBC instructions are executed (in the decimal

mode), one instruction cycle (such as an NOP) is needed before

the SEC, CLC, or CLD instruction is executed.

(4) An NOP instruction is needed immediately after the execution of

a PLP instruction.

(5) In order to avoid noise and latch-up, connect a bypass capacitor

(≈ 0.1 µF) directly between the VCC pin–VSS pin and the VCC pin–

CNVSS pin, using a thick wire.

AUTO-CLEAR CIRCUIT

When a power source is supplied, the auto-clear function will oper-

______

ate by connecting the following circuit to the RESET pin.

DISPLAY OSCILLATION CIRCUIT

The CRT display clock oscillation circuit has a built-in clock oscilla-

tion circuits, so that a clock for CRT display can be obtained simply

by connecting an LC, an RC, a quartz-crystal oscillator or a ceramic

resonator across the pins OSC1 and OSC2. Which of the sub-clock

or the display oscillation circuit is selected by setting bits 0 and 1 of

the CRT clock selection register (address 020916).

DATA REQUIRED FOR MASK ORDERS

The following are necessary when ordering a mask ROM produc-

tion:

(1) Mask ROM Order Confirmation Form

(2) Mark Specification Form

(3) Data to be written to ROM, in EPROM form (32-pin DIP type

27C101, three identical copies)

PROM Programming Method

The built-in PROM of the One Time PROM version (blank) and the

built-in EPROM version can be read or programmed with a general-

purpose PROM programmer using a special programming adapter.

The PROM of the One Time PROM version (blank) is not tested or

screened in the assembly process nor any following processes. To

ensure proper operation after programming, the procedure shown in

Figure 82 is recommended to verify programming.

Functional check in target device

Caution : The screening temperature is far higher

than the storage temperature. Never

expose to 150°C exceeding 100 hours.
