(1/6) × 9 × [TC/R] × 200 = 1/70
[TC/R] = 48, so TC/R = 2FH

9.1.5 Display Mode Setting Example 3: Combining Three Graphics Layers
• Conditions
• 320 × 200 pixels, single-panel drive (1/
200 duty cycle)
• First layer: graphics display
• Second layer: graphics display
• Third layer: graphics display
• Display memory allocation
• All layers (graphics): 320/8 = 40 charac-
ters per line, 200/1 = 200 lines. Required
memory size = 40 × 200 = 8000 bytes.
