Possible causes when the loop marked *1 or *3 takes a long time (2 or 3 seconds or more)
Oscillation is impeded by a leak due to a dirty PC board. Clean the PC board.
The capacitance of the capacitor for oscillation is inadequate. Consult the crystal
manufactuer.
Possible causes why the frequency counter is not stable.
The frequency counter is not adjusted. Observe the waveform at pin 1 on an oscilloscope.
The pattern layout is incorrect. See the description of "Pattern layout." Insert a bypass
capacitor having a capacitance of at least 1
μ
F between the V
DD
and V
SS
pins.
