ADV7180
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 contain
status bits from the ADV7180.
IDENTIFICATION
IDENT[7:0], Address 0x11 [7:0]
The register identification of the revision of the ADV7180. An
identification value of 0x18 indicates 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 infor-
mation 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. Consult 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.
