2. Opposite phase external clock
• When using an opposite phase external clock, X1 (X1A) must be supplied with a clock signal which has the
If the pins X0A and X1A are not connected to an oscillator, a pull-down resistor must be connected on the X0A
pin and the X1A pin must be left open.
If the PLL clock mode is selected and no external oscillator is operating or no external clock is supplied, the
microcontroller attempts to work with the free oscillating PLL. Performance of this operation, however, cannot
be guaranteed.

As a measure against power supply noise, it is required to connect a bypass capacitor of about 0.1 μF between

Noise at X0, X1 pins or X0A, X1A pins might cause abnormal operation. It is required to provide bypass capacitors
with shortest possible distance to X0, X1 pins and X0A, X1A pins, crystal oscillator (or ceramic resonator) and
ground lines, and, to the utmost effort, that the lines of oscillation circuit do not cross the lines of other circuits.
It is highly recommended to provide a printed circuit board art work surrounding X0, X1 pins and X0A, X1A pins
with a ground area for stabilizing the operation.
It is highly recommended to evaluate the quartz/MCU or resonator/MCU system at the quartz or resonator
manufacturer, especially when using low-Q resonators at higher frequencies.

It is also required to turn the digital power off after turning the A/D converter supply and analog inputs off. In this
case, the voltage must not exceed AVRH or AV
