Notes: 1. "Halted (retained)" means that internal register values are retained. The internal state is "operation suspended."
2. "Halted (reset)" means that internal register values and internal states are initialized.
3. In module stop mode, only modules for which a stop setting has been made are halted (reset or retained).
4. This function is not available in the H8S/2695.
5. Internal register values are retained because the H8S/2695 does not have a DTC.
6. With the exception of ports D and E, an I/O port always returns a value of 1 when read in the H8S/2633 Group and
H8S/2633R. Use as an output port is possible.
