TIMEOUT REGISTERS
When either the approaching or receding timeout elapses (that
is, after the defined number of CDC conversions is counted),
the data average (and thus the thresholds) is forced to follow the
new CDC data value immediately.
Ch1 Address Pointer 0x0A
Ch2 Address Pointer 0x0D
8 Bits, Read/Write, Factory Preset 0x86
When the timeout register equals 0, timeouts are disabled.

These registers set timeouts for the adaptive threshold mode.
The approaching timeout starts when the CDC data crosses the
data average ± sensitivity band toward the threshold, according
to the selected positive, negative, or window threshold mode.
The approaching timeout elapses after the number of conversion
cycles equals 2TimeOutApr, where TimeOutApr is the value of the four
most significant bits of the timeout register.

The receding timeout starts when the CDC data crosses the
data average ± sensitivity band away from the threshold,
according to the selected positive or negative threshold mode.
The receding timeout is not used in the window threshold
mode. The receding timeout elapses after the number of
conversion cycles equals 2TimeOutRec, where TimeOutRec is the
value of the four least significant bits of the timeout register.
