0x24—Bit[2] SOGIN1 Detection Bit
This bit is used to indicate when activity is detected on the
SOGIN1 input pin. If SOG is held high or low, activity is not
detected. The sync processing block diagram shows where this
function is implemented. 0 = SOGIN1 not active. 1 = SOGIN1
is active.

0x24—Bit[1] COAST Detection Bit
This bit detects activity on the EXTCK/COAST pin. It indicates
that one of the two signals is active, but it does not indicate
which one. A dc signal is not detected.

0x24—Bit[0] CLAMP Detection Bit
This bit is used to indicate when activity is detected on the
external CLAMP pin. If external CLAMP is held high or low,
activity is not detected.

0x25—Bit[1] Extraneous Pulses Detection
A second output from the Hsync filter, this status bit tells
whether extraneous pulses are present on the incoming sync
signal. Often extraneous pulses are used for copy protection, so
this status bit can be used for this purpose.
Table 76. Equalization Pulse Detect Bit
Detect
Result
0
No equalization pulses detected during active Hsync
1
Equalization pulses detected during active Hsync
HSYNC COUNT
0x26—Bits[7:0] Hsyncs per Vsync MSB
The 8 MSBs of the 12-bit counter that reports the number of
Hsyncs/Vsync on the active input. This is useful for determining
the mode and is an aid in setting the PLL divide ratio.
0x27—Bits[7:4] Hsyncs per Vsync LSBs
The 4 LSBs of the 12-bit counter that reports the number of
Hsyncs/Vsync on the active input.
TEST REGISTERS
0x28—Bits[7:0] Test Register 1
Must be written to 0xBF for proper operation.
0x29—Bits[7:0] Test Register 2
Must be written to 0x00 for proper operation.
0x2A—Bits[7:0] Test Register 3
Read-only bits for future use.
0x2B—Bits[7:0] Test Register 4
Read-only bits for future use.
