Since the main clock is used as the
clock for OSD, the oscillation
frequency is limited. Because of
this, the character size in width
(horizonal) 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.
However, it is not corresponding to the bi-scan
mode.
a ceramic resonator only for OSD and a
feedback resistor
a quartz-crystal oscillator only for OSD and a
feedback resistor
b1
The clock for OSD is supplied by connecting RC
or LC across the pins OSC1 and OSC2. However,
it is not corresponding to the bi-scan mode.

The clock for OSD is supplied by connecting LC
across the pins OSC1 and OSC2. In the bi-scan
mode, be sure to set this.
