For the resonator selection of the
780148(A), and 78F0148(A) and oscillator constants, users are required to
either evaluate the oscillation themselves or apply to the resonator
manufacturer for evaluation.
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/KF1 so that the internal operation
conditions are within the specifications of the DC and AC characteristics.

Be sure to connect the REGC pin of (A1) grade products directly to V
The external bus interface function cannot be used with (A1) grade products.
Be sure to connect the REGC pin of (A2) grade products directly to V
The external bus interface function cannot be used with (A2) grade products.
Do not use different soldering methods together (except for partial heating).
When the CPU is operating on the subsystem clock and the X1 input clock is
stopped (MCC = 1), do not access the registers listed above using an access
method in which a wait request is issued.
