Function Documentation

void hel_DmaCopy16 (  void *    pDest, const void *    pSrc, u32    SizeIn16BitWords )

Copy memory using DMA in 16bit mode. This function copies the data specified by pSrc to pDest using DMA channel 3 in 16bit mode Parameters: pDest  : Destination pSrc  : Source SizeIn16BitWords  : size of data to copy in 16bit words See also: hel_DmaCopy32()

void hel_DmaCopy32 (  void *    pDest, const void *    pSrc, u32    SizeIn32BitWords )

Copy memory using DMA in 32bit mode. This function copies the data specified by pSrc to pDest using DMA channel 3 in 32bit mode Parameters: pDest  : Destination pSrc  : Source SizeIn32BitWords  : size of data to copy in 32bit words See also: hel_DmaCopy16()

void hel_DmaSet16 (  void *    pDest, u16    SrcValue, u32    SizeIn16BitWords )

Set/Fill memory using DMA in 16bit mode. This function can be compared with "memset", but it uses DMA channel 3 in 16bit mode. Parameters: pDest  : Destination SrcValue  : Source-value SizeIn16BitWords  : size of data to set in 16bit words See also: hel_DmaSet32()

void hel_DmaSet32 (  void *    pDest, u32    SrcValue, u32    SizeIn32BitWords )

Set/Fill memory using DMA in 32bit mode. This function can be compared with "memset", but it uses DMA channel 3 in 32bit mode. Parameters: pDest  : Destination SrcValue  : Source-value SizeIn32BitWords  : size of data to set in 32bit words See also: hel_DmaSet16()
