The Comparator output can be polled in software, used as an interrupt source, and/or routed to a Port pin.
When routed to a Port pin, the Comparator output is available asynchronous or synchronous to the system
clock; the asynchronous output is available even in STOP mode (with no system clock active). When dis-
abled, the Comparator output (if assigned to a Port I/O pin via the Crossbar) defaults to the logic low state,
and the power supply to the comparator is turned off. See Section “21.3. Priority Crossbar Decoder” on
page 117 for details on configuring Comparator outputs via the digital Crossbar. Comparator inputs can be
externally driven from –0.25 V to (V
trical specifications are given in Section “7. Electrical Characteristics” on page 31.
The Comparator response time may be configured in software via the CPTnMD registers (see SFR Defini-
tion 12.2 and SFR Definition 12.4). Selecting a longer response time reduces the Comparator supply cur-
rent.
