GLOBAL STATUS REGISTERS
There are four registers that provide summary information
about the video decoder. The IDENT register allows the user to
identify the revision code of the ADV7183A. The other three
registers contain status bits from the ADV7183A.
IDENTIFICATION
IDENT[7:0] Address 0x11 [7:0]

locked (right now).
Depending on the setting of the FSCLE bit, the Status[0] and
Status[1] are based solely on horizontal timing info or on the
horizontal timing and lock status of the color subcarrier. See the
FSCLE FSC Lock Enable, Address 0x51 [7] section.
Autodetection Result
AD_RESULT[2:0] Address 0x10 [6:4]
The AD_RESULT[2:0] bits report back on the findings from
the autodetection block. Consult the General Setup section for
more information on enabling the autodetection block, and the
Autodetection of SD Modes section to find out how to
configure it.
