Transition
After power-on, transition to
the main run state
Reset during main run state
Transition from main run
state to PLL run state
Return to main run state
from PLL run state
Reset during PLL run state
*:The microcontroller operates using the main clock during the PLL clock oscillation stabilization wait state.
