The subsystem oscillator has a low amplification factor so as to lower the current consumption and is more

susceptible to noise than the main system clock oscillator. When using the subsystem clock circuit, therefore, utmost

care must be exercised in wiring the circuit.

If the oscillator does not operate correctly, the microcontroller cannot operate correctly, either. Consult the oscillator

manufacturer if you need an oscillation frequency at high accuracy.

VSS

Cautions 1. Keep the oscillator as close to the X1 and X2 (XT1 and XT2) pins as possible.

2. Do not pass any other signal lines through the region indicated by the dotted line.
