2588B–AVR–11/06
ACSRB – Analog Comparator Control and Status Register B
Table 18-2.
• Bit 7 – HSEL: Hysteresis Select
When this bit is written logic one, the hysteresis of the Analog Comparator is switched on. The
hysteresis level is selected by the HLEV bit.
• Bit 6 – HLEV: Hysteresis Level
When the hysteresis is enabled by the HSEL bit, the Hysteresis Level, HLEV, bit selects the hys-
teresis level that is either 20mV (HLEV=0) or 50mV (HLEV=1).
• Bit 2:0 – ACM2:ACM0: Analog Comparator Multiplexer
The Analog Comparator multiplexer bits select the positive and negative input pins of the Analog
Comparator. The different settings are shown in
