Notes: “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).
* The active or halted state can be selected by means of the MSTP0 bit in MSTPCR.
