FUNCTIONAL DESCRIPTION

I - Displayable Page Memory Map

The organization of a page-memory is shown in

Figure 7.

The display area consists of 25 rows of 40 charac-

ters per row.

The organization is as follows :

- Row zero contains the page header :

• The first seven characters (0 - 6) are used for

messages regarding the operational status.

• The eighth character is an alphanumeric control

character either "white" or "green" defining the

"search" status of the page. When it is "white"

the operational state is normal and the header

appears white ; when it is "green" the opera-

tional state corresponds to the "search mode"

and the header appears green.

• The following twenty-four characters give the

header of the requested page when the system

is in search mode.

• The last eight characters display the time of day.

- Row number twenty-four is used by the micro-

processor for the display of information, or used

to display X/24 colored key data according to

R0D7 bit.

- Row twenty-five comprises ten bytes of control

data concerning the received page (see Table 1)

and fourteen free bytes which can be used by the

microprocessor.
