I
Reset input terminal.
F.F. is reset when the terminal becomes
low-level and is set in the initial state.
When not used, the terminal should be
open or connected to VCC .
The reset is applied by rising VCC from a
voltage below 0.8 V (power-on reset
function).

C and R connection terminal.
The oscillation period is determined by
an external resistor and capacitor.
When applying a pulse to this terminal
from the outside, the voltage should be
within the range of 0 V to 3 V.

Oscillation frequency monitor terminal.
The output is given from the first stage
of F.F. and a frequency which is 1/2 of
the oscillation frequency fOSC is output-
ted. If not used, the terminal should be
open. This terminal is provided for con-
necting probe such as oscilloscope. Use
it with an output current under 100 µA.
