4 / 34 page LC87F6AC8A No.A0145-4/34 Interrupts: 27 sources, 10 vector addresses (LC876A00 compatible) 26 sources, 10 vector addresses (LC876B00 compatible) <1> Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt request of the level equal to or lower than the current interrupt is not accepted. <2> When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest level takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector address is given priority. * LC876A00 series compatible configuration No. Vector Address Level Interrupt Source 1 00003H X or L INT0 2 0000BH X or L INT1 3 00013H H or L INT2 / T0L / INT4 4 0001BH H or L INT3 / base timer / INT5 5 00023H H or L T0H / INT6 6 0002BH H or L T1L / T1H / INT7 7 00033H H or L SIO0 / T8L / T8H 8 0003BH H or L SIO1 9 00043H H or L ADC / MIC / T6 / T7 / PWM4 / PWM5 10 0004BH H or L VFD / port 0 / T4 / T5 * LC876B00 series compatible configuration No. Vector Address Level Interrupt Source 1 00003H X or L INT0 2 0000BH X or L INT1 3 00013H H or L INT2 / T0L / INT4 4 0001BH H or L INT3 / base timer / INT5 5 00023H H or L T0H / INT6 6 0002BH H or L T1L / T1H / INT7 7 00033H H or L SIO0 / T8L / T8H 8 0003BH H or L SIO1 / SIO2 9 00043H H or L ADC / MIC / T6 / T7 10 0004BH H or L VFD / port 0 / T4 / T5 • Priority levels X > H > L • When interrupts of the same level occur at the same time, the interrupt with the smallest vector address is given priority. Subroutine stack levels: Up to 2048 levels (The stack is allocated in RAM.) High-speed multiplication division instructions • 16 bits × 8 bits (5 tCYC execution time) • 24 bits × 16 bits (12 tCYC execution time) • 16 bits ÷ 8 bits (8 tCYC execution time) • 24 bits ÷ 16 bits (12 tCYC execution time) Oscillator circuits • RC oscillator circuit (internal) : For system clock • CF oscillator circuit : For system clock with internal Rf • Crystal oscillator circuit : For low-speed system clock with external Rd and Rf • Multifrequency oscillator circuit (internal) : For system clock |
