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.
Settings for (AFG1)3–0 have no effect unless Adaptive Mode
Control 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.
Settings for (AFG2)3–0 have no effect unless Adaptive Mode
Control is set to Mode B (MR56 = “1”).

ADAPTIVE FILTER GAIN 3
AFG3 (AFG3)7–0
(Address (SR5–SR0) = 24H)
This 8-bit-wide register is used to program the gain applied to
signals that lie above Adaptive Filter Threshold C.
Gain A and Gain B values vary from –8 to +7.
Settings for (AFG3)3–0 have no effect unless Adaptive Mode
Control is set to Mode B (MR56 = “1”).
The gain applied to signals that lie below Adaptive Threshold A
is 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 prepro-
grammed and become active whenever the threshold conditions
for the according register are met. To program the Adaptive
Filter Gain registers the same register settings are used as for the
Filter Gain register.

ADAPTIVE FILTER THRESHOLD A
AFTA AFTA7–0
(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.

ADAPTIVE FILTER THRESHOLD B
AFTB AFTB7–0
(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.
