Analog Devices 

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 ADV7189B. The other three registers

contain status bits from the ADV7189B.

IDENTIFICATION

IDENT[7:0] Address 0x11[7:0]

This register provides identification of the revision of

the ADV7189B.

An identification value of 0x11 indicates the ADV7189,

released silicon.

An identification value of 0x13 indicates the ADV7189B silicon.

STATUS 1

STATUS_1[7:0] Address 0x10[7:0]

This read-only register provides information about the internal

status of the ADV7189B. These bits are used to set VS free run

(coast) frequency. See the VS_C 16H oast[1:0], Address

0xF9[3:2]section and 162HCOL[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 information or

on the horizontal timing and lock status of the color subcarrier.

See the FSCLE 163H FSC Lock Enable, Address 0x51[7] section.

SD 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. For more information on enabling

the autodetection block, see the 164HGeneral Setup section. For

information on configuring it, see the Auto 165H detection of SD

Modes section.
