Lock-Related Controls
Lock information is presented to the user through Bits [1:0] of
Status Register 1. See the Status Register 1 [7:0], Address 0x10
[7:0] section. Figure 13 outlines the signal flow and the controls
that are available to influence how the lock status information is
generated.
SRLS, Select Raw Lock Signal, Address 0x51 [6]
Using the SRLS bit, the user can choose between two sources for
determining the lock status, which is indicated via Status Register 1,
Bits [1:0].

CIL[2:0], COL[2:0]
The TIME_WIN signal is based on a line-to-line evaluation of
the horizontal synchronization pulse of the incoming video. It
reacts quickly.
The FREE_RUN signal evaluates the properties of the incoming
video over several fields, taking vertical synchronization
information into account.
0 (default)—Selects the FREE_RUN signal.
1—Selects the TIME_WIN signal.
