3 / 32 page LC87FBH08A www.onsemi.com 3 AD converter: 12 bits/8 bits 11 channels Successive approximation 12 bits/8 bits AD converter resolution selectable Port input: 10 channels, Reference voltage input: 1 channel PWM: Multifrequency 12-bit PWM 2 channels Reference voltage generator circuit (VREF17) Capable of monitoring the power supply voltage by AD conversion of frequency variable RC oscillator circuit’s reference voltage. Remote Control Receiver Circuit (sharing pins with P73, INT3, and T0IN) Noise rejection function (noise filter time constant selectable from 1 tCYC, 32 tCYC, and 128 tCYC) Clock Output Function Capable generating clock outputs with a frequency of 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64 of the source clock selected as the system clock. Capable of generating the source clock for the subclock. Watchdog Timer Capable of generating an internal reset on an overflow of a timer running on the low-speed RC oscillator clock or subclock. Operating mode at standby is selectable from 3 modes (continue counting/stop operation/stop counting with a count value held). Interrupts 20 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 5 00023H H or L T0H 6 0002BH H or L T1L/T1H 7 00033H H or L SIO0/UART1 receive 8 0003BH H or L SIO1/UART1 transmit 9 00043H H or L ADC/T6/T7/ PWM4, PWM5 10 0004BH H or L Port 0 Priority levels X > H > L Of interrupts of the same level, the one with the smallest vector address takes precedence.
