8.11.3 Clock for OSD
As a clock for display to be used for OSD, it is possible to select one
of the following 4 types.
Main clock supplied from XIN pin
Main clock supplied from XIN pin divided by I.5
Clock from the ceramic resonator or the LC or oscillator from the
pins OSC1 and OSC2
Clock from the ceramic resonator or the quartz-crystal oscillator
supplied from the pins OSC1 and OSC2.
This OSD clock for each block can be selected by the OSD clock
selection register (address 00ED16).
When selecting the main clock, set the oscillation frequency to
8 MHz.

Since the main clock is used as the
clock for display, the oscillation
frequency is limited. Because of this,
the character size in width (horizontal)
direction is also limited. In this case,
pins OSC1 and OSC2 are also used
as input ports P33 and P34 respectively.
The clock for OSD is supplied by connecting the
following across the pins OSC1 and OSC2.
a ceramic resonator only for OSD
a quartz-crystal oscillator only for OSD and a
feedback resistor (See note)
