The frequency of the internal clock (Iφ) and peripheral clock (Pφ) can be changed either by
changing the multiplication rate of PLL circuit 1 or by changing the division rates of divider. All
of these are controlled by software through the frequency control register (FRQCR). The methods
are described below.
4.5.1
A PLL settling time is required when the multiplication rate of PLL circuit 1 is changed. The on-
chip WDT counts the settling time.
1. In the initial state, the multiplication rate of PLL circuit 1 is 1 time.
2. Set a value that will become the specified oscillation settling time in the WDT and stop the
3. Set the desired value in the STC[2:0] bits. The division ratio can also be set in the IFC[2:0] and
4. This LSI pauses temporarily and the WDT starts incrementing. The internal and peripheral
5. Supply of the clock that has been set begins at WDT count overflow, and this LSI begins

clocks both stop and the WDT is supplied with the clock. The clock will continue to be output
at the CKIO pin. This state is the same as software standby mode. Whether or not registers are
initialized depends on the module. For details, see section 25, Power-Down Modes.
