Description
Trigger Sense
The TSEN field specifies the sense of the comparator output that
generates an ADC event. The sense conditioning is as follows:
Value Description
0x0 Level sense, see TSLVAL
0x1 Falling edge
0x2 Rising edge
0x3 Either edge
0
Interrupt Sense Level Value
Value Description
0 An interrupt is generated if the comparator output is Low.
1 An interrupt is generated if the comparator output is High.
0x0
Interrupt Sense
The ISEN field specifies the sense of the comparator output that
generates an interrupt. The sense conditioning is as follows:
Value Description
0x0 Level sense, see ISLVAL
0x1 Falling edge
0x2 Rising edge
0x3 Either edge
0
Comparator Output Invert
Value Description
0 The output of the comparator is unchanged.
1 The output of the comparator is inverted prior to being processed
by hardware.
0
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.
