Display clock selection bits
Refer to Table 10.
Fix these bits to “0.”
(10) Clock for Display
As a clock for display to be used for CRT display, it is possible to
select one of the following 4 types.
Main clock supplied from the X
IN
pin
Main clock supplied from the X
IN
pin divided by 1.5
Clock from the LC or RC supplied from the pins OSC1 and OSC2.
Clock from the ceramic resonator or quartz-crystal oscillator sup-
plied from the pins OSC1 and OSC2.
This clock for display can be selected for each block by the CRT
clock selection register (address 00ED
16
).
When selecting the main clock, set the oscillation frequency to
8 MHz.

Functions
The clock for display is supplied by connecting RC or LC across the pins OSC1 and OSC2.
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 P3
3
and P3
4
respectively.
The clock for display is supplied by connecting the following across the pins OSC1 and OSC2.
a ceramic resonator only for CRT display and a feedback resistor
a quartz-crystal oscillator only for CRT display and a feedback resistor (Note)
Note:
It is necessary to connect other ceramic resonator or quartz-crystal oscillator across the pins X
IN
and X
OUT
.
