4 / 36 page LC87F17C8A www.onsemi.com 4 ■ Clock Output Function <1> Can output a clock with a clock rate of 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, or 1/64 of the source oscillator clock selected as the system clock. <2> Can output the source oscillator clock for the subclock. ■ Interrupts 49 sources, 10 vectors <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 level 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 lowest vector address is given priority. No. Vector Level Interrupt Source 1 00003H X or L INT0 2 0000BH X or L INT1 3 00013H H or L INT2/T0L/INT4/UHC-A bus active/UHC-B bus active/USB bus active/remote control receive 4 0001BH H or L INT3/INT5/base timer/AIF asynchronous counter 5 00023H H or L T0H/INT6/UHC-A device connected, disconnected, resumed/SMIIC1 6 0002BH H or L T1L/T1H/INT7/AIF start/SMIIC0/UHC-B device connected, disconnected, resumed/ AIF FIFO empty 7 00033H H or L SIO0/USB bus reset/USB suspend/SCUART2 receive completed/SCUART2 receive FIFO full 8 0003BH H or L SIO1/SIO4/USB endpoint/USB-SOF/ SCUART2 buffer empty/SCUART2 transmission completed/AIF end 9 00043H H or L ADC/T6/T7/UHC-ACK/UHC-NAK/UHC error/UHC-STALL 10 0004BH H or L Port 0/PWM0/PWM1/T4/T5/UHC-SOF/CRC Priority levels X > H > L When interrupts of the same level occur at the same time, the interrupt with the lowest vector address is given priority. ■ Subroutine Stack Levels : Up to 4096 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 Circuit and PLL Medium-speed RC oscillator circuit (internal): For system clock (approx. 1 MHz) Low-speed RC oscillator circuit (internal) : For system clock, timer, and watchdog timer (approx. 30 kHz) CF oscillator circuit : For system clock Crystal oscillator circuit : For system clock and time-of-day clock PLL circuit (internal) : For USB interface (see Fig. 5) and audio interface (see Fig. 6) ■ Internal Reset Functions Power-on reset (POR) function <1> POR is activated at power-on. <2> POR release voltage can be selected from 8 levels (1.67V, 1.97V, 2.07V, 2.37V, 2.57V, 2.87V, 3.86V, and 4.35V) by setting options. Low voltage detection reset (LVD) function <1> LVD and POR functions are combined to generate resets when power is turned on and when power voltage falls below a threshold level. <2> The use/disuse of the LVD function and the low voltage threshold level (7 levels: 1.91V, 2.01V, 2.31V, 2.51V, 2.81V, 3.79V, and 4.28V) can be selected by setting options. |
