The on-chip oscillator frequency is gained by the expression below. Since the input-capture input
is sampled by the
5.5
There are two methods to supply external clock pulses into this LSI: connecting a crystal or
ceramic resonator, and an external clock. Oscillation pins OSC1 and OSC2 are common with
general ports PC0 and PC1, respectively. To set pins PC0 and PC1 as crystal resonator or external
clock input ports, refer to section 5.2.4, Clock Control/Status Register (CKCSR).
5.5.1
Figure 5.11 shows an example of connecting a crystal resonator. An AT-cut parallel-resonance
crystal resonator should be used. Figure 5.12 shows the equivalent circuit of a crystal resonator. A
resonator having the characteristics given in table 5.1 should be used.
