Notes: 1. "Halted (retained)" means that the operation of the internal state is suspended, although
internal register values are retained.
2. "Halted (reset)" means that internal register values and internal state are initialized.
3. In module standby mode, only modules for which a stop setting has been made are
halted (reset or retained).
4. There are two types of on-chip peripheral module registers; ones which are initialized in
software standby mode and module standby mode, and those not initialized those
modes. For details, refer to appendix A.3, Register States in Each Operating Mode.
5. The port high-impedance bit (HIZ) in SBYCR sets the state of the I/O port in software
standby mode. For details on the setting, refer to section 24.2.1, Standby Control
Register (SBYCR). For the state of pins, refer to appendix B, Pin States.
