8.14 OSD CLOCK GENERATING CIRCUIT
When generate OSD clock based on main clock, set resistor and
capacity to FILT pin as shown in Fig.8.14.1.
Set bit 0 of the clock control register 1 (address 00CD16) to operate
OSD clock generating circuit “0.” Clock control register 1 (address
00CD16) is shown in Fig.8.14.3. Then, clock frequency for OSD is set
up by the clock frequency register (address 021016).
Clock frequency setting register is shown in Fig.8.14.2.

In order to generate normally oscillation frequency for OSD shown in
Table 8.14.1, be sure to set the main clock f (XIN) to 8MHz. Then, set
up not any values other than these.
When not using OSD clock function,the low-power dissipation can
relize by setting bit0 of the clock control register to “1.”
