GX_SetDefaultDMA

Syntax

#include <nitro/gx/gx.h>

u32 GX_SetDefaultDMA(u32 dma_no);

Arguments

dma_no The DMA number to use with GX.

Return Values

Returns the settings before this function was called.
Returns GX_DMA_NOT_USE if NDMA had been configured to be used instead of DMA.

Description

Changes the DMA number used by the GX function. Specify GX_DMA_NOT_USE in the argument to use neither DMA nor NDMA.

Note: Because this function causes DMA to be used instead of the NDMA configured by the GX_SetDefaultNDMA function, it deletes the values set by GX_SetDefaultNDMA.
