1.11. Analog Comparators
Two analog comparators with dedicated input pins are included on-chip. The comparators have software
programmable hysteresis and response time. Each comparator can generate an interrupt on a rising edge,
falling edge, or both. The interrupts are capable of waking up the MCU from sleep mode, and Comparator
0 can be used as a reset source. The output state of the comparators can be polled in software or routed to
Port I/O pins via the Crossbar. The comparators can be programmed to a low power shutdown mode when
not in use.
