This comparator is not only a single comparator. It consists of 16-R resistor string, 3-channel input and optional
external comparison reference source input. The 16-R resistor string acts as 16-level voltage divider which top
voltage reference can be selected from VDD or 2.5V ref. Use above register bits to set the whole job. This
comparator is used to some applications such as voltage detection, RSSI level, sensor output level and other slow
signal level transition detection and so on. This comparator can be called a simple 4-bit low speed ADC but the
sampling time is decided by software. For AC frequency detection, it is limited by it output comparator structure.
We suggest the detected AC frequency below 1kHz.
