Description
The ISLVAL bit specifies the sense value of the input that
generates an interrupt if in Level Sense mode. If 0, an
interrupt is generated if the comparator output is Low.
Otherwise, an interrupt is generated if the comparator output
is High.
The ISEN field specifies the sense of the comparator output
that generates an interrupt. The sense conditioning is as
follows:
The CINV bit conditionally inverts the output of the
comparator. If 0, the output of the comparator is unchanged. If
1, the output of the comparator is inverted prior to being
processed by hardware.
Reserved bits return an indeterminate value, and should
never be changed.
