(Note)1. Component chooses the most suitable constant of C1,C2,C3,C4 and
C5 according to the noise level and noise frequency of a power supply.
Depending on the noise level of a power supply, and noise frequency, a noise may
be unable to be removed only by capacitor of a standard circuit.
At this time, pulses other than a signal may be outputted from a RXD
terminal in a specific communication distance.
Please confirm with the system that it is satisfactory with each transmission speed
in all communication distance at the time of examination.
When there is a noise ingredient which cannot be removed only by C1,C2,C3,
please insert RX(1 to 10Ω) and it after a check.
When there is a problem, please use it after a check as a noise measure Circuit.
2.Don’t connect an Avcc terminal with power supply because it is the connection
of only capacitor.
