| 0x0D800000 | IPC | reg 0: request pointer | To make an IOS request, the physical address of an IOS command struct is written here by the Broadway. Then, Broadway sets bit 0 of IPC reg 1 to indicate a request is ready. | |
| 0x0D800004 | IPC | reg 1: semaphore flags | Broadway sets bits here as "doorbells" to indicate status; Starlet responds by setting flags here. | |
| 0x0D800008 | IPC | reg 2: Reply pointer | When an IOS request has completed, IOS will modify the original command struct passed in IPC reg 0, copy that pointer to reg 2, then set reg 1 to 0x14 to indicate a reply is ready. |
