23.3.6 Interrupts and PRS Output
23.3.7 Output to GPIO
2010-09-06 - d0001_Rev1.00
Figure 23.3. 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. When the ACMPPEN bit is set, the selected pin will be set as output regardless
of the pin configuration in GPIO. The output to the GPIO can be inverted by setting the GPIOINV bit
in ACMPn_CTRL.
