Register Name
Function
Preset Value
A-SYNC
Automatic sync processing mode.
Sync processing mode is changed in accordance with the results obtained by the
internal format detection circuits. Format detection is performed for a SYNC or
HD/VD signal selected by SYNC SW. The result of detection is returned to H, V
FORMAT and H, V FM2.
The HV FREQ setting is invalid when this mode is active.
0: OFF (manual switching mode by HV FREQ setting)
1: ON
OFF
(0)
S MODE
Switches sync output mode.
This function sets the dummy HD/VD output mode when there is no input. The
frequency of the dummy HD/VD output depends on the HV FREQ setting (when
A-SYNC = OFF) or H, V FORMAT (when A-SYNC = ON).
H, V IN shows whether there is no input or not.
0: OFF (No HD and free-run VD output (approx. 44 Hz), when there is no input.
However, in 1250i mode, no HD and no VD output, when there is no input.)
1: ON (Dummy HD/VD output when there is no input)
OFF
(00)
CLAMP
Switches Y clamping mode.
This function sets the clamping mode for pins 5, 14, 39.
0: SYNC TIP CLAMP
1: BIAS
SYNC TIP
(0)
HV-POL
Switches the polarity of the HD/VD output.
This function sets the polarity of HD/VD OUT (pins 29, 30).
0: Positive
1: Negative
Positive
(0)
VD PHS
Switches the phase of dummy VD output.
VD PHS compensates for delay time so that the dummy VD-OUT phase is the
same as that form the separated V-sync.
0: No delay
1: 0.2 H delay (0.15 H delay for 1125/50p)
No-delay
(0)
Read Mode
Register Name
Function
LINE1
LINE1 detection for D-pin (for the number of lines)
00: 525 (480)
01: 750 (720)
10: ----
11: 1125 (1080)
Detects the voltage of LINE1 selected by YCbCr SW. 11 is returned when the pin is not connected.
LINE2
LINE2 detection for D-pin (for i/p)
0: Interlace
1: Progressive
Detects the voltage of LINE2 selected by YCbCr SW. 1 is returned when the pin is not connected.
LINE3
LINE3 detection for D-pin (for aspect ratio)
00: 4:3
01: 4:3 letter box
10: ----
11: 16:9
Detects the voltage of LINE3 selected by YCbCr SW. 11 is returned when the pin is not connected.
SW LINE1
SW LINE1 (pin 48) detection for D-pin
0: Connected
1: Not connected
SW LINE2
SW LINE1 (pin 9) detection for D-pin
0: Connected
1: Not connected
HD-POL
Polarity detection to HD-IN
0: Positive
1: Negative
Detects the width from the HD-IN pin to determine whether it is negative or not. When the High level of
the input HD-IN is wider than approx 14
s, HD-POL shows 1.
