Input and output pins for the main clock generating circuit.
Feedback resistor is built in between X
IN
pin and X
OUT
pin.
Connect a ceramic resonator or a quartz-crystal oscillator between the X
IN
and X
OUT
pins to set the
oscillation frequency.
If an external clock is used, connect the clock source to the X
IN
pin and leave the X
OUT
pin open.
This pin determines the oscillation between X
IN
and X
OUT
. The oscillation method can be selected from
either by an oscillator or by a resistor.
Input and output pins for sub-clock generating circuit. (Connect a quartz-crystal oscillator between the
X
CIN
and X
COUT
pins to set the oscillation frequency. The clock generated the externals cannot be input
directly.)
Reference voltage input pin for LCD.
The input voltage to this pin is boosted threefold by voltage multiplier.
