Notes:
- All digital input pins should be not left floating.
- VSS1 -5 must be connected to the same ground plane.
- Connect a 1μF (± 30%; including temperature characteristics) capacitor between the VD18 pin and DVSS. When
this capacitor is polarized, the positive polarity pin should be connected to the VD18 pin.
- Refer to Table 5 for the equivalent series resistance R1 and capacitance C values of the X’tal oscillator.
