ThrFixed
ThrFixed = 1 sets the fixed threshold mode; the outputs reflect the comparison of data and a fixed (constant)
value of the threshold registers.
ThrFixed = 0 sets the adaptive threshold mode; the outputs reflect the comparison of data to the adaptive
thresholds. The adaptive threshold is set dynamically, based on the history of the previous data.

Description
0
Idle
The part is fully powered up, but performing no conversion.
0
1
Continuous
Conversion
The part is repeatedly performing conversions on the
enabled channel(s); if two channels are enabled, the part is
sequentially switching between them.
0
1
0
Single conversion
The part performs a single conversion on the enabled
channel; if two channels are enabled, the part performs two
conversions, one on each channel. After finishing the
conversion(s), the part goes to the idle mode.
0
1
Power-down
The part powers down the on-chip circuits, except the
digital interface.
