Active
Interface
Bit 7—AIO: Active Interface Override. If set to Logic 1, the user
can select the active interface via Bit 6. If set to Logic 0, the active
interface is selected via Bit 3 in Register 11H.
Bit 6—AIS: Active Interface Select. Logic 0 selects the analog inter-
face as active. Logic 1 selects the digital interface as active. Note:
The indicated interface will be active only if Bit 7 is set to Logic 1
or if both interfaces are active (Bits 6
or
7
and
4 = Logic 1 in
Register 11H).
Bit 5—Active Hsync Override. If set to Logic 1, the user can select
the Hsync to be used via Bit 4. If set to Logic 0, the active interface
is selected via Bit 2 in Register 11H.
Bit 4—Active Hsync Select. Logic 0 selects Hsync as the active
sync. Logic 1 selects Sync-on-Green as the active sync. Note: The
indicated Hsync will be used only if Bit 5 is set to Logic 1 or if
both syncs are active (Bits 6, 7 = Logic 1 in Register 11H.)
Bit 3—Active Vsync Override. If set to Logic 1, the user can select
the Vsync to be used via Bit 2. If set to Logic 0, the active interface
is selected via Bit 1 in Register 11H.
Bit 2—Active Vsync Select. Logic 0 selects Raw Vsync as the
output Vsync. Logic 1 selects Sync Separated Vsync as the output
Vsync. Note: The indicated Vsync will be used only if Bit 3 is set
to Logic 1.
Bit 1—Coast Select. Logic 0 selects the coast input pin to be used for
the PLL coast. Logic 1 selects Vsync to be used for the PLL coast.
Bit 0—
PWRDN
. Full Chip Power-Down, active low. (Logic 0 =
Full Chip Power-Down, Logic 1 = Normal.)

Threshold
Sync Separator Threshold—Sets how many pixel clocks the sync
separator will count to before toggling high or low. This should be
set to some number greater than the maximum Hsync or equaliza-
tion pulsewidth.

Control Bits
Bit 4—Test Bit. (Must be set to 1 for proper operation of chip.)
Bit 2—Scan Enable. (Logic 0 = Not Enabled, Logic 1 = Enabled.)
Bit 1—Coast Polarity Override. (Logic 0 = Polarity determined by
chip, Logic 1 = Polarity set by Bit 6 in Register 0Fh.)
Bit 0– Hsync Polarity Override. (Logic 0 = Polarity determined by
chip, Logic 1 = Polarity set by Bit 7 in Register 0Fh.)
