FRAME CONTROL & TIMING
Figure 7 shows the composition of display frame with the OSD characters.
Figure 7. Frame Composition with the OSD Characters
User can determine the dot frequency by the equation of H freq. x the number of horizontal resolution.
And the number of horizontal resolution is determined by the bit9 - 8 (dot 1,dot 0) of the frame Control registers-1.
If dot 0 = “0”, dot 1 = “0”, then the dot frequency is calculated by the equation of H freq.
×
320.
If the H freq. = 15 kHz, then the dot frequency is 15 kHz
×
320 = 4.8 MHz.
If dot 0 = “1”, dot 1 = “1” and the horizontal frequency is 120 kHz, then the dot frequency is 120 kHz
×
800 = 96
MHz. 96 MHz is the maximum clock frequency in this processor.
