ADV7180
Data Sheet
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.

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
