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
161H
VS_Coast[1:0], Address
0xF9[3:2]section and
162H
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 information or
on the horizontal timing and lock status of the color subcarrier.
See the
163H
FSCLE 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
164H
General Setup section. For
information on configuring it, see the
165H
Autodetection of SD
Modes section.
