Input hysteresis
Power consumption vs. propagation delay
Register Description
ACnCTRL – Analog Comparator n Control Register
Figure 27-2. Analog Comparator Window Mode
Application software can select between no, low, and high hysteresis. Adding hysteresis can
avoid constant toggling of the output if the input signals are very close to each other and some
noise exists in either of the signals or in the system.
It is possible to enable High-speed mode to get the shortest possible propagation delay. This
mode consumes more power than the default Low-power mode that has a longer propagation
delay.
• Bits 7:6 - INTMODE[1:0]:Analog Comparator Interrupt Modes
These bits configure the interrupt mode for Analog Comparator n according to
Table 27-1.
