No.6829-21/22

• Other note on all oscillator circuit:

• Place the lines for signals that can easily change suddenly, high amplitude signals connected to the higher capacity voltage

(+15 V) ports, and powerful current supplies as far as possible from the oscillation circuit, and do not cross these lines

with lines concerned to the clock.

3. RES : Reset Pin

• The length of line (Lres) between the RES pin and the external circuit should be as short as possible.

• The length of lines (L1 and L2) between the RES pin and the capacitor (Cres), and the VSS and the capacitor should

be as short as possible.

4. TEST : Test Pin

• The length of line (L) between the VSS and the TEST pin should be as short as possible.

• The TEST pin and the VSS pin should be connected as close as possible to the VSS pin.

5. AD0 to AD7 : Analog Input Pins

The connection for the analog input pins, such as A/D converter input pins and comparator input pin, should meet the

following conditions.

• The length of the line (L1) between the damping resistor (R1) and each analog pins should be as short as possible.

• The capacitor added between each analog pins and AV- pin (base voltage input pin for A/D converter) should be located

as close as possible to the AV- input pin.

6. I/O Pins

All I/O pins on these microcontrollers have function of both input and output.

• When used as an input pin, add a damping resistor and keep the length of the line to that pin as short as possible.
