32.8 CMP Functional Description
The Comparator can be used to compare two analog input voltages applied to INP and
INM. The analog comparator output (CMPO) is high when the non-inverting input is
greater than the inverting input, and is low when the non-inverting input is less than the
inverting input. This signal can be selectively inverted by setting CR1[INV] = 1.
The SCR[IER], SCR[IEF], and SCR[SMELB] bits are used to select the condition which
will cause the comparator module to assert an interrupt to the processor. SCR[CFF] is set
on a falling edge and SCR[CFR] is set on rising edge of the comparator output. The
(optionally filtered) comparator output can be read directly through the SCR[COUT] bit.

Plus Input MUX Control
Determines which input is selected for the plus input of the comparator. For INx inputs, refer to CMP, DAC
and ANMUX Blocks Diagram.
