DESCRIPTION

The STV5347 teletext decoder is computer-con­trolled.It can storeeither 4 teletext pages without
ghostrow,or 2 teletextpageswithghostrows.Data
slicing and capturing extracts the teletext informa­tionembedded in thecompositevideo signal. Con­trolisaccomplishedviaatwowireserialI
Chip address is 22h. Internal ROM provides a
character set suitable to display text using up to
sevennationallanguages.Hardware andsoftware
features allow selectable master/slave synchroni­zationconfigurations.The STV5347also supports
facilities for reception and display of current level
protocoldata.

Thedisplay areaconsists of25 rowsof 40 charac­ters per row.

Theorganization isas follows:

• The first seven characters (0 - 6) are used for
messagesregarding the operationalstatus.

• The eighthcharacteris an alphanumericcontrol
character either“white” or “green” defining the
“search” status of the page. When it is “white”
the operational state is normal and the header
appears white ; when it is “green” the opera-

RegistersR0 to R10 are write only whilst R11Ais
a read/writeandR11Bis read only.
Theautomatic succession on a byte bybyte basis
is indicatedby the arrowsin Table3.
In the normaloperatingmode TB shouldbe set to
logic level 0.

(continued)

(seeTable3)

Afterpower-up the contentsof the registersare as
follows: allbitsin registersR0 toR11Aare cleared
to zero with the exception of bits D0 and D1 in
registersR5 and R6 which are set to logicalone.
After power-upall the memorybytes are preset to
hexadecimalvalue 20H(space)with theexception
of the byte correspondingto row 0 of column 7 of
chapter 0 which is set to the value corresponding
to “alphawhite” hexadecimalvalue 07H.
In 4 pages mode, R1D4(ghost row enable) is set
to ’0’. In this mode, the X/24, X/26, X/27, X/28
packets of the selectedpages,and the 8/30pack­ets, are not stored.
In 2 pages mode, R1D4(ghost row enable) is set
’1’. In this mode two displayable pages can be
storedinchapter0and1,andthe ghostrowsofthe
selected pages, and the 8/30 packets, are stored
in chapter4 and 5.
