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
page 144
externally driven from –0.25 V to (V
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.
