Description
Reserved bits return an indeterminate value, and should
never be changed.
The ASRCP field specifies the source of input voltage to the
VIN+ terminal of the comparator. The encodings for this field
are as follows:
Reserved bits return an indeterminate value, and should
never be changed.
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:
