 Configurable hysteresis.
 Configurable speed and consumption.
 Each comparator has configurable analog input source.
– DAC output
– CMP input pins
– The whole or sub-multiple values of internal reference voltage.
 Window comparator.
 Outputs to I/O.
 Outputs to timers for triggering.
 Outputs to EXTI.
