MI_Init

Syntax

#include <nitro/mi.h>

void MI_Init( void );

Arguments

None.

Return Values

None.

Description

Performs MI-related initialization.

This function is called internally by the OS_Init function, so there is no need for the application to call it again. (For ARM9 only. This function is not called from OS_Init() on ARM7.)

Specifically, the following actions are performed: Items with the NITRO logo ( ) show the behavior in NITRO mode, and items with the TWL logo ( ) show the behavior in TWL mode.

ARM9
The shared WRAM (WRAM-0/1) is entirely allocated to ARM7.
( MI_SetWramBank( MI_WRAM_ARM7_ALL ) )
Initializes the new DMA.
( MI_InitNDma() )
Reliably initializes DMA0. This is done as a workaround for DMA hardware bugs.
( MI_StopDma( 0 ) )



ARM7
Initializes the new DMA.
( MI_InitNDma() )
Reliably initializes DMA0. This is done as a workaround for DMA hardware bugs.
( (MI_StopDma( 0 ) )
