ABLIC S-35720
The S-35720 Series compares the timer value and the value set to the SET0 pin and the SET1 pin, and outputs a wake-up signal (interrupt signal) when the values match each other. The timer of the S-35720 is a 24-bit binary-up counter. After the RST pin changes from "L" to "H", the S-35720 Series takes the values set to the SET0 pin and the SET1 pin.FEATURES
