VCS received with 60Hz frequency (D7 = 1)or 50Hz (D7
= 0). Only valid when VCS is good (D0 = 1)

The abbreviations have the same significance as in Table 1 with the exception of the ”DO CARE” entries. It is only
when this bit is ”1” that the corresponding digit istaken 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
2
C bus is automatic.

CHARACTER SETS
The complete character set with 8-bit decoding is
given in Tables4a, 4b and4c.
Characters in columns 0 and 1 are normally dis-
played asblanks. Blackdots representthe charac-
ter shape whereas white dots represent the
background.
Each character can be identified byapair of corre-
sponding row and column integers : for example
the character”3” maybe indicatedby 3/3.
Arectangle may be representedas follows :
The characters 8/6, 8/7, 9/5, 9/7 are used as spe-
cial characters, always in conjunctionwith 8/5.
The 13 national characters are placed in columns
with bit 8 = 0.
