Function
Compares the internal power supply (voltage set for V by the CRS3
IH
to CRS0 bits) and electric potential of the COMP pin.
No hysteresis.
Compares the internal power supply and electric potential of the
COMP pin.
With hysteresis. V_IH and V_IL are set by the CRS3 to CRS0 bits.
Compares the electric potential of the VCref and COMP pins.
No hysteresis.
