(2) Noise countermeasures
1) SK noise
If there is noise in the rise of the SK clock input, the system may recognize more clocks than were actually input,
and malfunctioning may occur because of offset bits.
2) VCC noise
Noise and surges in the power supply line can cause malfunctioning. To eliminate these factors, we recommend
installing a bypass capacitor between the power supply and the ground.
