GLOBAL STATUS REGISTERS
Three registers provide summary information about the video
decoder: Status Register 1, Status Register 2, and Status Register 3.
These registers contain status bits that report operational information
to the user.
Status Register 1 [7:0], Address 0x10 [7:0]
This read-only register provides information about the internal
status of the ADV7188. See the CIL [2:0], Count-Into-Lock,
Address 0x51 [2:0] and the COL [2:0], Count-Out-of-Lock,
Address 0x51 [5:3] sections for information on the timing.
Depending on the setting of the FSCLE bit, the IN_LOCK [0] and
LOST_LOCK [1] bits of Status Register 1 are based solely on the
horizontal timing information or on the horizontal timing and
lock status of the color subcarrier. See the FSCLE, F Lock
Enable, Address 0x51 [7]
AD_RESULT [2:0], Autodetection Result, Address 0x10 [6:4]
These bits report the findings from the autodetection block. For
more information on enabling the autodetection block, see the

Description
Horizontal lock indicator (instantaneous).
Gemstar detect.
Flags whether 50 Hz or 60 Hz is present at output.
Indicates if a CVBS signal is detected in composite/S-video autodetection configuration
Indicates if the ADV7188 is in free-run mode. Outputs a blue screen by default. See the
DEF_VAL_AUTO_EN, Default Value Automatic Enable, Address 0x0C [1] section for details
about disabling this function.
