The abbreviations have the same significance as inTable 1 with the exception of the ”DO CARE” entries. It isonly when this bit is ”1”
that the corresponding digit is taken into consideration onpage request. For example, a page definedas ”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
2
C is automatic.

IV - Character Sets
The complete character set with 8-bit decodingis
given in Tables 4, 5 and 6.
Characters in columns 0 and 1 are normally dis-
played asblanks. Black dotsrepresentthe charac-
ter shape whereas white dots represent the
background.
Each charactercan be identified by 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, alwaysin conjunctionwith 8/5.
The 13 national characters are placed in columns
with bit 8 = 0.
