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 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

C is automatic.

Table 4 :
Register R3
V - Character Sets
The complete character set with 8-bit decoding is
given in Table 5.
Characters in columns 0 and 1 are normally dis-
played as blanks. Black dots represent the charac-
ter shape whereas white dots represent the
background.
Each character can be identified by a pair of corre-
sponding row and column integers : for example
the character "3" may be indicated by 3/3.
A rectangle may be represented as follows :
The characters 8/6, 8/7, 9/5, 9/7 are used as spe-
cial characters, always in conjunction with 8/5.
The 13 national characters are placed in columns
with bit 8 = 0.
