Notes:
* The internal register values are retained and internal states are initialized.
Halted (Retained) in the table means that internal register values are retained and
internal operations are suspended.
Halted (Reset) in the table means that internal register values and internal states are
initialized.
In module stop mode, only modules for which a stop setting has been made are halted
(reset or retained).
Notes:
: Transition after exception handling
* NMI,
