Settings initialization reset (INIT) state
In the settings initialization reset (INIT) state, all settings are initialized. This state occurs if a settings
initialization reset (INIT) request is accepted or the hardware standby state is ended.
Execution of a program on the CPU is stopped and the program counter is initialized. All peripheral circuits
are initialized. The oscillation circuit runs, but the PLL stops running. All internal clocks are stopped while
the "L" level is input to the external INIT pin; otherwise, they run.
A settings initialization reset (INIT) and an operation initialization reset (RST) are outputted to the internal
circuits.
If a settings initialization reset (INIT) request no longer exists, the state is cleared and the oscillation
stabilization wait reset (RST) state is entered. Then, the operation initialization reset (RST) state is entered
and the settings initialization reset sequence is executed

Priority of state transition requests
In any state, state transition requests conform to the priority listed below. However, some requests that
occur only in a specific state are valid only in that state.
[Highest]
[Lowest]
Settings initialization reset (INIT) request
End of oscillation stabilization wait time (occurs only in the oscillation stabilization
wait reset state and the oscillation stabilization wait RUN state)
Operation initialization reset (RST) request
Valid interrupt request (occurs only in the RUN, sleep, and stop states)
Stop mode request (writing to a register) (occurs only in the RUN state)
Sleep mode request (writing to a register) (occurs only in the RUN state)
