Pin Descriptions
5V regulator output (control circuit
power supply)
For stable operation, pin should be
connected to ground via a capacitor
(0.1
μF or more).
Pin 2: Quartz oscillator input. Maximum
oscillation frequency is 10 MHz
Pin 3: Quartz oscillator output
Generates reference clock. When an
external clock (several MHz) is used,
connect a resistor of about 13 k
in
series to the X
I pin, so that the signal is
input via the resistor. Leave the X
O pin
open.
Start/stop pin
Low: Start
High: Stop
High when open.
Divisor selector pin
"L": (divisor 3072): 0 to 1.0V
"M": (divisor 1024): 2.0 to 3.0V
"H": (divisor 4093): 4.0V to V
REG
High when open.
