To flash selected characters, the MPU can alternately write the characters as character
codes and blank characters at intervals of 0.5 to 1.0 seconds.
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.
