39.5.7 Comparator Output

The output of each comparator can be routed to an I/O pin by setting the Output bit group in the Comparator Control x register (COMPCTRLx.OUT). To get the analog comparator output on the I/O line, CFGCON1.CMP0_OE/CFGCON1.CMP1_OE also needs to be set or enabled. This allows the comparator to be used by external circuitry. Either the raw, non-synchronized output of the comparator or the GCLK_AC-synchronized version, including filtering, can be used as the I/O signal source. The output appears on the corresponding AC_CMPx pin. The AC_CMP1 can be output on an alternate pin by configuring the CFGCON0.ACCMP1_ALTEN configuration.
