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.
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:
ASRCP Function
00
Pin value
01
Pin value of C0+

TSLVAL
R/W
0
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.

TSEN
R/W
0
The TSEN field specifies the sense of the comparator output that
generates an ADC event. The sense conditioning is as follows:
TSEN Function
00 Level sense, see TSLVAL
01 Falling edge
10 Rising edge
11 Either edge
