LC865520B/16B/12B/08B/04B

(11) Interrupt

- 13-source and 10-vectored interrupt function:

1. External interrupt INT0 (including watchdog timer)

2. External interrupt INT1

3. External interrupt INT2, Timer/counter T0L (lower 8 bits of Timer 0)

4. External interrupt INT3, Base timer

5. Timer/counter T0H (upper 8 bits of Timer 0)

6. Timer T1L (lower 8 bits of Timer 1), Timer T1H (upper 8 bits of Timer 1)

7. Serial interface SIO0

8. Serial interface SIO1

9. AD converter

10. Port 0

- Built-in Interrupt Priority control register

Three interrupt priorities are supported (low, high and highest) and multi-level nesting is possible. Low or high

priority level can be assigned to the 11 interrupt sources of interrupts 3 to 10 shown above by the interrupt priority

control register. For the external interrupt INT0 and INT1(interrupt 1 and 2), low or highest can be set regardless of

the interrupt priority register.

(12) Sub-routine stack levels

- A maximum of 128 levels (set stack inside RAM)

(13) Multiplication and division

16 bits × 8-bit (7 instruction-cycle-times)

16 bits / 8-bit (7 instruction-cycle-times)

(14) 3 types of oscillation circuits

- Built-in RC oscillation circuit used for the system clock.

- CF oscillation circuit used for the system clock.

- Crystal oscillation circuit used for the system clock and the time-base clock.

(15) Standby function

- HALT mode

The HALT mode stops the program execution, which minimizes power consumption. This operation mode can be

released by a system reset or an interrupt request.

- HOLD mode

The HOLD mode stops all oscillation circuits: CF, RC and Crystal oscillations. This mode can be released by the

following conditions.

• Feed "L" level to the reset terminal ( RES )

• Feed the selected level to P70/INT0, P71/INT1 terminals

• Feed "L" level to the Port 0

(16) Shipping form

• DIP42S

• QIP48E
