REGISTER FUNCTIONS
Register
R9 to R11A
Address
09H to 0BH*
Function
Active row address (R9), activecolumn address (R10).
Data contained in R11A read (written) from (to) memory by microprocessor via I
2
C.
Bit(s)
Description
R11B
Address
0BH*
Status
VCS Signal
Quality (D0)
60Hz (D7)
Good VCS quality signal detected (D0 = 1) or disturbed (D0 = 0)
VCS received with 60Hz frequency (D7 = 1) or 50Hz (D7 = 0).
Only valid when VCS is good (D0 = 1)
* Readingof R11A orR11B is determined by register 0, bit D0. Nevertheless, write operation is always performed on R11A register.

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 Table 4.
Characters in columns 0 and 1 are normally dis-
playedasblanks.Black dotsrepresent the charac-
ter shape whereas white dots represent the
background.
Each charactercan be identifiedby apairof corre-
sponding row and column integers : for example
the character ”3” may be indicated by 3/3.
Arectangle may be represented as follows :
The characters 8/6, 8/7, 9/5, 9/7 are usedas spe-
cial characters,always in conjunction with 8/5.
The 13 nationalcharacters are placed in columns
withbit 8 = 0.
