2.5.2 OSD Oscillation Circuit
Figure 2.5.3 shows the block diagram of the main clock generating circuit.
The OSD clock oscillation circuit can obtain simply a clock for OSD by connecting an LC oscillator or a
ceramic resonator (or a quartz-crystal oscillator) across the pins OSC1 and OSC2. Which of LC oscillator
or a ceramic resonator (or a quartz-crystal oscillator) is selected by setting bits 1 and 2 of the clock control
register (address 0205
