GLOBAL STATUS REGISTER
Four registers provide summary information about the video
decoder. The IDENT register allows the user to identify the
revision code of the ADV7180. The other three registers (0x10,
0x12, and 0x13) contain status bits from the ADV7180.
IDENTIFICATION
IDENT[7:0], Address 0x11[7:0]
This is the register identification of the ADV7180’s revision.
Table 19 describes the various versions of the ADV7180.

STATUS 1
Status 1[7:0], Address 0x10[7:0]
This read-only register provides information about the internal
status of the ADV7180.
See the CIL[2:0], Count Into Lock, Address 0x51[2:0] section
and the COL[2:0], Count Out of Lock, Address 0x51[5:3]
section for details on timing.
Depending on the setting of the FSCLE bit, the Status Register 0
and Status Register 1 are based solely on horizontal timing
information 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
ADV7180 autodetection block. See the General Setup section for
more information on enabling the autodetection block and the
Autodetection of SD Modes section for more information on
how to configure it.
