COMPARATOR ANALOG BLOCK
Selectable 0 mV, 10 mV ( 5 mV), and 20 mV ( 10 mV), 40 mV ( 20 mV) input
hysteresis.
Five selectable external voltages; fully configurable on either positive or negative
input channel.
Internal voltage reference from band gap and temperature sensor selectable on either
positive or negative input channel.
32-stage voltage ladder with the internal reference voltage selectable on either the
positive or the negative input channel. See
Voltage ladder source voltage is selectable from an external pin or the main 3.3 V
supply voltage rail.
Voltage ladder can be separately powered down for applications only requiring the
comparator function.
Interrupt output is connected to NVIC.
Comparator level output is connected to output pin ACMP_O.
Comparator output is internally connected to the ADC and DAC and can be used to
trigger a conversion.
The comparator output is also connected internally to capture channel 3 on each of
the 32-bit and 16-bit counter/timers.
