osPiGetStatusFormat#include <ultra64.h> u32 osPiGetStatus(void);What These Functions Do The osPiRawStartDma, osPiRawWriteIo, osPiRawReadIo, and osPiGetStatus provide low-level, unmanaged access to the peripheral interface (PI). The peripheral interface (PI) is responsible for the transport of data between RDRAM and bulk-storage devices (BSD) such as ROM, RAM, CD-ROM, and other technologies. These functions provide low-level, unmanaged access to the PI; that is, they do not use the PI manager. These functions should be used only when it is ensured that there is no other services using the PI. For this reason, Nintendo strongly recommends that "cooked" or managed, high-level PI access routines be used for most purposes; see osPiStartDma for details on this functionality. The raw routines may be useful, however, immediately after the application boot procedure is entered and before the operating system is initialized. The osPiGetStatus routine returns the hardware status of PI. The 32-bit returned value contains the following bit patterns:
