3.5.3 Control Register Definitions
The host interface internal registers are divided into two classes: User
Configurable (UC) and Auto-Configurable (AC). Address locations 0 through 6
contain parameters which may be configured by the user.
Locations 7 through 31 are automatically configured based on the STD[4:0] and
MODE registers, but can be user configured if desired.

.
00000
5
MODE
UC
Enables (MODE=1) or bypasses (MODE=0) the GF9331
processing.
0
1
0
VM_CTL
UC
Enables (VM_CTL=1) or bypass (VM_CTL=0) vertical
motion detection.
0
1
EDGE_CTL
UC
Enables (EDGE_CTL=1) or bypasses (EDGE_CTL=0)
edge detection.
0
6
CC_BLANK_EN
UC
Enables (CC_BLANK_EN=1) or bypasses
(CC_BLANK_EN=0) blanking in the close captioned video
region.
0
12
FVH_EN
UC
Enables the GF9331 to use external F_IN, V_IN, H_IN
controls (FVH_EN=1) in place of embedded TRS
(FVH_EN=0).
0
13
F_POLARITY
UC
When set to '1', F_IN follows normal convention where
F_IN is '0' for field 1 (odd) and '1' for field 2 (even).
1
14
V_POLARITY
UC
Defines the polarity of the V_IN pin. When set to '1', V_IN
follows normal convention where V_IN is HIGH in the
vertical blanking region.
1
15
H_POLARITY
UC
Defines the polarity of the H_IN pin. When set to '1', H_IN
follows normal convention where H_IN is HIGH in the
horizontal blanking region.

7:0
F_OFFSET_EVEN[7:0]
UC
Defines the number of lines from the F_IN pin EAV transition
to the
vertical blanking interval following the even field. This
parameter has a maximum value of 255.
00000000
15:8
F_OFFSET_ODD[7:0]
UC
Defines the number of lines from the F
_IN
pin EAV
transition to the vertical blanking interval following the odd
field. This parameter has a maximum value of 255.
00000000

7:0
V_OFFSET_EVEN[7:0]
UC
Defines the number of lines from the V
_IN
pin EAV
transition to the end of the even active video field region.
This parameter has a maximum value of 255.
00000000
15:8
V_OFFSET_ODD[7:0]
UC
Defines the number of lines from the V
_IN
pin EAV
transition to the end of the odd active video field region.
This parameter has a maximum value of 255.
