Comparator outputs can be polled in software, used as an interrupt source, and/or routed to a Port pin.
When routed to a Port pin, Comparator outputs are 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 supply current falls to less than 100 nA. See

trical specifications are given in Table 7.1.
Comparator response time may be configured in software via the CPTnMD registers (see SFR Definition
7.3 and SFR Definition 7.6). Selecting a longer response time reduces the Comparator supply current. See
Table 7.1 for complete timing and supply current specifications.
