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

Description
0
Idle
Part is fully powered up but performing no conversion.
0

Continuous
Conversion
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
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.
