22.3.6 Interrupts and PRS Output
22.3.7 Output to GPIO

Figure 22.3. Capacitive Sensing Set-up
The analog comparator includes an edge triggered interrupt flag (EDGE in ACMPn_IF). If either IRISE
and/or IFALL in ACMPn_CTRL is set, the EDGE interrupt flag will be set on rising and/or falling edge
of the comparator output respectively. An interrupt request will be sent if the EDGE interrupt flag in
ACMPn_IF is set and enabled through the EDGE bit in ACMPn_IEN. The edge interrupt can also be
used to wake up the device from EM3-EM1.
The analog comparator also includes an interrupt flag, WARMUP in ACMPn_IF, which is set when
a warm-up sequence has finished. An interrupt request will be sent if the WARMUP interrupt flag in
ACMPn_IF is set and enabled through the WARMUP bit in ACMPn_IEN.
The synchronized comparator outputs are also available as a PRS output signals.
The output from the comparator and the capacitive sense output are available as alternate functions to
the GPIO pins. Set the ACMPPEN bit in ACMPn_ROUTE to enable output to pin, and the LOCATION
bits to select output location. The GPIO-pin must also be set as output. The output to the GPIO can be
inverted by setting the GPIOINV bit in ACMPn_CTRL.
