Notes: "Halted (retained)" means that internal register values are retained. The internal state is
"operation suspended."
"Halted (reset)" 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).
* When the LCD is operated in watch, subactive, or subsleep mode, select the subclock as
the clock to be used.
