Description
Reserved bits return an indeterminate value, and should
never be changed.
The TOEN bit enables the ADC event transmission to the
ADC. If 0, the event is suppressed and not sent to the ADC. If
1, the event is transmitted to the ADC.
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 TSLVAL bit specifies the sense value of the input that
generates an ADC event if in Level Sense mode. If 0, an ADC
event is generated if the comparator output is Low. Otherwise,
an ADC event is generated if the comparator output is High.
The TSEN field specifies the sense of the comparator output
that generates an ADC event. The sense conditioning is as
follows:
