4 / 29 page LC878496PB/C8PB/G0PB/G1PB/J2PB/J3PB/M4PB/P6PB/P7PB No.A1795-4/29 ■Interrupts • 29 sources, 10 vector addresses 1) Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt requests of the level equal to or lower than the current interrupt are 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 takes precedence. 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/INT5/Base timer (BT0, 1) 5 00023H H or L T0H/INT6 6 0002BH H or L T1L/T1H/INT7 7 00033H H or L SIO0/UART1 receive/UART2 receive 8 0003BH H or L SIO1/SIO2/UART1 transmit/UART2 transmit 9 00043H H or L ADC/T6/T7/PWM4, PWM5 10 0004BH H or L Port 0/T4/T5/PWM0, PWM1 • Priority levels X > H > L • Of interrupts of the same level, the one with the smallest vector address takes precedence. • The Base timers are two interrupt sources of BT0 and BT1, it is one interrupt source by PWM0 and 1, it is one interrupt source by PWM4 and 5. ■Subroutine Stack Levels • 6144 levels maximum (1/2 of capacity of RAM, 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) ■Oscillation Circuits • RC oscillator circuit (internal): For system clock • CF oscillator circuit: For system clock with internal Rf and external Rd • Crystal oscillator circuit: For time-of-day clock, for low-speed system clock with internal Rf and external Rd • Multifrequency RC oscillator circuit (internal): For system clock ■System Clock Divider Function • Can run on low current. • The minimum instruction cycle selectable from 222ns, 444ns, 888ns, 1.78μs, 3.55μs, 7.10μs, 14.2μs, 28.4μs, and 56.8 μs.(at a main clock of 13.5MHz) |
