GLOBAL STATUS REGISTERS
Four registers provide summary information about the video
decoder. The IDENT register allows the user to identify the
revision code of the ADV7181. The other three registers contain
status bits from the ADV7181.
IDENTIFICATION
IDENT[7:0] Address 0x11 [7:0]
Provides identification of the revision of the ADV7181. Review

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 sec-tion for
more information on enabling the autodetection block, and the
Autodetection of SD Modes section to find out how to
configure it.
