Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Trigger Output Enable
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.
Analog Source Positive
The ASRCP field specifies the source of input voltage to the VIN+ terminal
of the comparator. The encodings for this field are as follows:
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Trigger Sense Level Value
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.
