Description
Reserved
These bits enable read/write operations, but the write
value should always be 0.
System Clock (Iφ) Select
These bits select the frequency of the system clock
provided to the CPU, DTC, and DMAC. The ratio to the
input clock is as follows:
000: × 4
001: × 2
010: × 1
011: × 1/2
100: Setting prohibited
101: Setting prohibited
110: Setting prohibited
111: Setting prohibited
The frequencies of the peripheral module clock and
external bus clock change to the same frequency as the
system clock if the frequency of the system clock is lower
than that of the two clocks.

This bit enables read/write operations, but the write value
should always be 0.
