Bit 0—Reserved
This bit is reserved. Never write 1 to this bit, as it can cause the LSI to malfunction.
4.2
Clock pulses can be supplied to the system clock divider either by connecting a crystal or ceramic
oscillator, or by providing external clock input. As shown in figure 4.2, the H8/38124 Group
supports selection between a system clock oscillator and an on-chip oscillator. See section 4.2,
On-Chip Oscillator Selection Method, for information on selecting the on-chip oscillator.
Connecting a Crystal Oscillator
Figure 4.3(1) shows a typical method of connecting a crystal oscillator to the H8/38024 or
H8/38024R Group, and figure 4.3(2) shows a typical method of connecting a crystal oscillator to
the H8/38024S and H8/38124 Group.
