is in searchmode.
The lasteightcharactersdisplaythetime ofday.
- 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 concerningthe received page (see Table 1)
and fourteenfreebyteswhichcan beusedbythe
microprocessor.
