ADAPTIVE FILTER GAIN 1
AFG1 (AFG1)7–0
(Address (SR5–SR0) = 22H)
This 8-bit-wide register is used to program the gain applied to signals
which lie above Adaptive Filter Threshold A but are smaller than
Adaptive Filter Threshold B.
Gain A and Gain B values vary from –8 to +7. The individual
responses are shown in the figures below.
Settings for (AFG1)3–0 have no effect unless Adaptive Mode Con-
trol is set to Mode B (MR56 = “1”).

(Address (SR5–SR0) = 23H)
This 8-bit-wide register is used to program the gain applied
to signals which lie above Adaptive Filter Threshold B but are
smaller than Adaptive Filter Threshold C.
Gain A and Gain B values vary from –8 to +7. The individual
responses are shown in the figures below.
Settings for (AFG2)3–0 have no effect unless Adaptive Mode Con-
trol is set to Mode B (MR56 = “1”).

AFG3 (AFG3)7–0
(Address (SR5–SR0) = 24H)
This 8-bit-wide register is used to program the gain applied to signals
which lie above Adaptive Filter Threshold C
Gain A and Gain B values vary from –8 to +7. The individual
responses are shown in the figures below.
Settings for (AFG3)3–0 have no effect unless Adaptive Mode Con-
trol is set to Mode B (MR56 = “1”).
The gain applied to signals which lie below Adaptive Threshold A
are programmed in the Filter Gain register.
At any one time only one of the following registers is active: AFG1,
AFG2, AFG3, FG. The gain values can be preprogrammed and
become active whenever the threshold conditions for the accord-
ing register is met. To program the Adaptive Filter Gain registers
the source register settings are used as for the Filter Gain register
.

ADAPTIVE FILTER THRESHOLD A
AFTA (AFTA)7–0
(Address (SR5–SR0) = 25H)
This 8-bit-wide register is used to program the threshold value for
small edges. The recommended programmable threshold range is
from 16–235, although any value in the range of 0–255 can be used.

AFTB (AFTB)7–0
(Address (SR5–SR0) = 26H)
This 8-bit-wide register is used to program the threshold value for
medium edges and has priority over Adaptive Threshold A. The
recommended programmable threshold range is from 16–235,
although any value in the range of 0–255 can be used.

(Address (SR5–SR0) = 27H)
This 8-bit-wide register is used to program the threshold value
for large edges and has priority over Adaptive Threshold A and B.
The recommended programmable threshold range is from 16–235,
although any value in the range of 0–255 can be used.
