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 its supply current falls to less than 100 nA. See
page 131
externally driven from –0.25 V to (V
trical specifications are given in Table 7.1.
The Comparator response time may be configured in software via the CPTnMD registers (see SFR Defini-
tion 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 current consumption specifications.
