When switching the CPU clock's clock source, wait until oscillation of the switch destination is stable
before switching sources.
Notes on Power Control
•
•
Insert four or more NOP instructions following the WAIT instruction. When entering wait mode,
because the instruction queue prefetches instructions that follow the WAIT instruction, prefetched
instructions are sometimes executed prior to the interrupt routine used to exit wait mode.
The following is an example program for entering wait mode:
FSET
WAIT

Do not enter wait mode when the FMR23 bit in the FMR2 register is 1 (low current consumption
read mode enabled). To enter wait mode, set the FMR23 bit to 0 (low current consumption read
mode disabled) and the FMR01 bit to 0 (CPU rewrite mode disabled), disable DMA transfer, then
execute the WAIT instruction.
