Description

Although this bit is readable/writable, only 0 should be
written to.
External Bus Clock (Bφ) Select
These bits select the frequency of the external bus
clock. The ratio to the input clock is as follows:
BCK (2:0) MD_CLK = 0
000:
001:
010:
011:
1XX:
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.
