and local bus interface. The division ratio is specified by the CK0 and CK1 bits of the standby control register (STBC).
Also, the operating speed can be selected to match the supply voltage.
the division ratio, depending on the clock selected before change.
ratio until the division ratio has been completely changed.
The frequency divider performs 1/2, 1/4, 1/8 or 1/16 scaling of the clock oscillator output, and supplies the resulting clock to
Controlling the division ratio to match the speed required by the CPU enables the overall power consumption to be reduced.
When RESET is input, the lowest speed (1/16) is selected.
If the division ratio of the frequency divider circuit is changed, the maximum time shown in Table 4-1 is required to change
Instruction execution continues even while the division ratio is changed, and the clock is supplied with the previous division
