16.5.2.2. Graph display
To present two overlaid graphs on the screen, configure
the display as for the menu bar display and put one graph
on each screen layer. The difference in contrast between
the half- and full-intensity displays will make it easy to
16.5.3. Flashing areas
16.5.3.1 Small area
To flash selected characters, the MPU can alternately
write the characters as character codes and blank charac-
ters at intervals of 0.5 to 1.0 seconds.

1. OVLAY: P1 = 00H
2. DISP ON/OFF: P1 = 34H
16.5.3.2. Large area
Divide both layer 1 and layer 2 into two screen blocks
each, layer 2 being divided into the area to be flashed and
the remainder of the screen. Flash the layer 2 screen
block at 2 Hz for the area to be flashed and combine the
layers using the OR function.
16.6.2. Kanji character display
The program for writing large characters operates as
follows:
1. The microprocessor reads the character data from its
