Cautions
•
The read from the external memory space 0–4 cache-through area and the write to the
frequency modification register should be performed in on-chip X/Y memory. After reading
from the external memory space 0–4 cache-through area, do not perform any write operations
in external memory spaces 0–4 until the write to the frequency modification register.
•
When the write access to the frequency modification register is executed, the WDT starts
automatically.
•
Do not turn off the CKIO output when PLL circuit 1 is in the operating state.
•
The CKIO output will be unstable until the PLL circuit stabilizes.
•
When a frequency is modified, halt the on-chip DMAC (E-DMAC and DMAC) operation
before the frequency modification.
