3 / 21 page LC865520B/16B/12B/08B/04B No.6697-3/21 (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 (17) Development tools Evaluation (EVA) chip : LC866096 EPROM version : LC86E5420 One time version : LC86P5420 Emulator : EVA-86000 + ECB867100 (Evaluation chip board) + POD865400 (POD) |
