Table 23.1 Damping Resistance Value
Notes: 1. The H8S/2258 Group is out of operation.
Figure 23.3 shows the equivalent circuit of the crystal resonator. Use a crystal resonator that has
the characteristics shown in table 23.2.

23.2.2
An external clock signal can be input as shown in the examples in figure 23.4. If the XTAL pin is
left open, ensure that stray capacitance does not exceed 10 pF. When complementary clock is
input to the XTAL pin, the external clock input should be fixed high in standby mode, subactive
mode, subsleep mode, or watch mode.
