ADV7181B
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 ADV7181B. The other three registers
contain status bits from the ADV7181B.
Rev. 0 | Page 17 of 96
IDENTIFICATION
IDENT[7:0] Address 0x11 [7:0]
The register identification of the revision of the ADV7181B.
An identification value of 0x11 indicates the ADV7181, released
silicon.
An identification value of 0x13 indicates the ADV7181B.
STATUS 1
STATUS_1[7:0] Address 0x10 [7:0]
This read-only register provides information about the internal
status of the ADV7181B.
See CIL[2:0] Count Into Lock, Address 0x51 [2:0] and COL[2:0
Count Out of Lock, Address 0x51 [5:3] for information on the
timing.
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
ADV7181B 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.
