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 P36 and P37 respectively.
The clock for OSD is supplied by connecting the
following across the pins OSC1 and OSC2.
a ceramic resonator only for OSD and a feedback
resistor
a quartz-crystal oscillator only for OSD and a
feedback resistor (See note)
