Note 2) There is a tolerance of approximately 1% between the center frequency at the ceramic resonator mode and the
nominal value presented by the ceramic resonator supplier. For details, refer to the specification for the ceramic
resonator.
The min., max. values of OSC frequency represent the oscillatable frequency range.
Note 3) When using the piggyback microcomputer, evaluation chip for evaluation, connect a feedback resistor (approxi-
mately lM
).
