The abbreviations have thesame significance as inTable 1 with the exception of the “DO CARE” entries.It is only when this bit is “1”
that the corresponding digit is taken into consideration on page request.For example, a page defined as ”normal” or one defined as
“timed” may be selected.
If “HOLD” is low the page is held. The addressing of successive bytes via the I

V - CharacterSets
The complete character set with 8-bit decodingis
given in Table5.
Characters in columns 0 and 1 are normally dis-
playedasblanks.Blackdots representthe charac-
ter shape whereas white dots represent the
background.
Eachcharactercan beidentifiedby apair of corre-
sponding row and column integers : for example
the character “3” may be indicatedby 3/3.
Arectangle may be representedas follows :
The characters8/6, 8/7, 9/5, 9/7 are used as spe-
cial characters,always in conjunctionwith 8/5.
The 13 nationalcharacters are placed in columns
with bit 8 = 0.
