SYNC PROCESSING
0x20—Bit[2] PLL Sync Filter
This bit selects which signal the PLL uses. It can select between
either raw Hsync or SOG or filtered versions. The filtering of
the Hsync and SOG can eliminate nearly all extraneous
transitions, which have traditionally caused PLL disruption.
The power-up default setting is 0.

0x20—Bit[1] Sync Processing Input Source
This bit selects whether the sync processor uses a raw sync or a
regenerated sync for the following functions: coast, H/V count,
field detection and Vsync duration counts. Using the
regenerated sync is recommended.

0x23—Bits[7:0] Sync Filter Window Width
This 8-bit register sets the window of time for the regenerated
Hsync leading edge (in 25 ns steps) and that sync pulses are
allowed to pass through. Therefore with the default value of 10,
the window width is ±250 ns. The goal is to set the window
width so that extraneous pulses are rejected. (see the Sync
Processing section). As in the sync separator threshold, the
25 ns multiplier value is somewhat variable. The maximum
variability over all operating conditions is ±20% (20 ns to 30 ns).
DETECTION STATUS
0x24—Bit[7] HSYNC0 Detection Bit
This bit is used to indicate when activity is detected on the
HSYNC0 input pin. If Hsync is held high or low, activity is not
detected. The sync processing block diagram shows where this
function is implemented. 0 = HSYNC0 not active. 1 = HSYNC0
is active.

0x24—Bit[6] HSYNC1 Detection Bit
This bit is used to indicate when activity is detected on the
HSYNC1 input pin. If Hsync is held high or low, activity is not
detected. The sync processing block diagram shows where this
function is implemented. 0 = HSYNC1 not active. 1 = HSYNC1

0x24—Bit[5] VSYNC0 Detection Bit
This bit is used to indicate when activity is detected on the
VSYNC0 input pin. If Vsync is held high or low, activity is not
detected. The sync processing block diagram shows where this
function is implemented. 0 = VSYNC0 not active. 1 = VSYNC0
