Note that full field detection (lines other than VBI lines) of any
standard can also be enabled by writing into the VBI_DATA_
P24_N22[3:0] and VBI_DATA_P337_N285[3:0] registers. So, if
VBI_DATA_P24_N22[3:0] is programmed with any teletext
standard, then teletext is decoded off for the entire odd field.
The corresponding register for the even field is VBI_DATA_
P337_N285[3:0].
For teletext system identification, VDP assumes that if teletext
is present in a video channel, all the teletext lines comply with a
single standard system. Therefore, the line programming using
the VBI_DATA_Px_Ny and VBI_DATA_Px registers identifies
whether the data in line is teletext; the actual standard is
identified by the VDP_TTXT_TYPE_MAN bit.
To program the VDP_TTXT_TYPE_MAN bit, the
VDP_TTXT_TYPE_MAN_ENABLE bit must be set to 1.
