VDP_TTXT_TYPE_MAN_ENABLE, Enable Manual
Selection of Teletext Type, Address 0x60[2], User Sub Map
Setting VDP_TTXT_TYPE_MAN_ENABLE to 0 (default), the
manual programming of the teletext type is disabled.
Setting VDP_TTXT_TYPE_MAN_ENABLE to 1, the manual
programming of the teletext type is enabled.
VDP_TTXT_TYPE_MAN[1:0], Specify the Teletext Type,
Address 0x60[1:0], User Sub Map
These bits specify the teletext type to be decoded. These bits are
functional only if VDP_TTXT_TYPE_MAN_ENABLE is set to 1.

VDP Ancillary Data Output
Reading the data back via I
standards with high data rates (for example, teletext). An alternative
is to place the sliced data in a packet in the line blanking of the
digital output CCIR656 stream. This is available for all standards
sliced by the VDP module.
When data is sliced on a given line, the corresponding ancillary
data packet is placed immediately after the next EAV code that
occurs at the output (that is, data sliced from multiple lines are
not buffered up and then emitted in a burst). Note that, due to
the vertical delay through the comb filters, the line number on
which the packet is placed differs from the line number on
which the data was sliced.
The user can enable or disable the insertion of VDP results that
have been decoded into the 656 ancillary streams by using the
ADF_ENABLE bit.
ADF_ENABLE, Enable Ancillary Data Output Through
656 Stream, Address 0x62[7], User Sub Map
Setting ADF_ENABLE to 0 (default) disables the insertion of
VBI decoded data into the ancillary 656 stream.

Setting ADF_ENABLE to 1 enables the insertion of VBI
decoded data into the ancillary 656 stream.
The user may select the data identification word (DID) and the
secondary data identification word (SDID) through programming
the ADF_DID[4:0] and ADF_SDID[5:0] bits, respectively.
ADF_DID[4:0], User-Specified Data ID Word in Ancillary
Data, Address 0x62[4:0], User Sub Map
This bit selects the data ID word to be inserted into the ancillary
data stream with the data decoded by the VDP.
The default value of ADF_DID[4:0] is 10101.
ADF_SDID[5:0], User-Specified Secondary Data ID Word
in Ancillary Data, Address 0x63[5:0], User Sub Map
These bits select the secondary data ID word to be inserted in
the ancillary data stream with the data decoded by the VDP.
The default value of ADF_SDID[5:0] is 101010.
DUPLICATE_ADF, Enable Duplication/Spreading of
Ancillary Data over Y and C Buses, Address 0x63[7], User
Sub Map
This bit determines whether the ancillary data is duplicated
over both Y and C buses or if the data packets are spread
between the two channels.
When DUPLICATE_ADF to 0 (default) is set, the ancillary data
packet is spread across the Y and C data streams.
When DUPLICATE_ADF to 1 is set, the ancillary data packet is
duplicated on the Y and C data streams.
ADF_MODE[1:0], Determine the Ancillary Data Output
Mode, Address 0x62[6:5], User Sub Map
These bits determine whether the ancillary data output mode is
in byte mode or nibble mode.
