Description
Peripheral Module Clock (Pφ) Select
These bits select the frequency of the peripheral module
clock. 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 frequency of the peripheral module clock should be
lower than that of the system clock. Though these bits
can be set so as to make the frequency of the peripheral
module clock higher than that of the system clock, the
clocks will have the same frequency in reality.
Reserved
This bit enables read/write operations, but the write value
should always be 0.
External Bus Clock (Bφ) Select
These bits select the frequency of the external bus clock.
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 frequency of the external bus clock should be lower
than that of the system clock. Though these bits can be
set so as to make the frequency of the external bus clock
higher than that of the system clock, the clocks will have
the same frequency in reality.
