Input the clock from the X1 pin during on-chip debugging.
Control the X1 and X2 pins by externally pulling down the P31 pin.

Product quality may suffer if the absolute maximum rating is exceeded even
momentarily for any parameter. That is, the absolute maximum ratings are
rated values at which the product is on the verge of suffering physical
damage, and therefore the product must be used under conditions that
ensure that the absolute maximum ratings are not exceeded.
When using the crystal/ceramic oscillator, wire as follows in the area
enclosed by the broken lines in the above figures to avoid an adverse effect
from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines.
• Do not route the wiring near a signal line through which a high fluctuating
• Always make the ground point of the oscillator capacitor the same potential
• Do not ground the capacitor to a ground pattern through which a high
• Do not fetch signals from the oscillator.
Since the CPU is started by the internal oscillation clock after reset, check
the oscillation stabilization time of the high-speed system clock using the
oscillation stabilization time counter status register (OSTC). Determine the
oscillation stabilization time of the OSTC register and oscillation stabilization
time select register (OSTS) after sufficiently evaluating the oscillation
stabilization time with the resonator to be used.
The oscillator constants shown above are reference values based on
evaluation in a specific environment by the resonator manufacturer. If it is
necessary to optimize the oscillator characteristics in the actual application,
apply to the resonator manufacturer for evaluation on the implementation
circuit. The oscillation voltage and oscillation frequency only indicate the
oscillator characteristic. Use the 78K0/KE1+ so that the internal operation
conditions are within the specifications of the DC and AC characteristics.
