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

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

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
