Field Documentation

unsigned int IRES_EDMA3CHAN_PaRamStruct::opt

Channel options.

Remarks:

Transfer configuration options.

unsigned int IRES_EDMA3CHAN_PaRamStruct::src

Channel source address.

Remarks:

The byte address from which data is transferred.

unsigned short IRES_EDMA3CHAN_PaRamStruct::acnt

Count for first dimension.

Remarks:

Unsigned value specifying the number of contiguous bytes within an array (first dimention of the transfer).

Valid values range from 1 to 65535 inclusive.

unsigned short IRES_EDMA3CHAN_PaRamStruct::bcnt

Count for second dimension.

Remarks:

Unsigned value specifying the number of arrays in a frame, where an array is acnt bytes.

Valid values range from 1 to 65535 inclusive.

unsigned int IRES_EDMA3CHAN_PaRamStruct::dst

Channel destination address.

Remarks:

The byte address to which data is transferred.

unsigned short IRES_EDMA3CHAN_PaRamStruct::srcElementIndex

Source bcnt index.

Remarks:

Signed value specifying the byte address offset between source arrays within a frame (2nd dimension).

Valid values range from -32768 to 32767 inclusive.

unsigned short IRES_EDMA3CHAN_PaRamStruct::dstElementIndex

Destination bcnt index.

Remarks:

Signed value specifying the byte address offset between destination arrays within a frame (2nd dimension).

Valid values range from -32768 to 32767 inclusive.

unsigned short IRES_EDMA3CHAN_PaRamStruct::link

Link address.

Remarks:

The PaRAM address containing the PaRAM set to be linked (copied from) when the current PaRAM set is exhausted.

A value of 0xffff specifies a null link.

unsigned short IRES_EDMA3CHAN_PaRamStruct::bCntrld

bcnt reload.

Remarks:

The count value used to reload bcnt when bcnt decrements to 0 (TR is submitted for the last array in 2nd dimension).

This is only relevant in A-synchronized transfers.

unsigned short IRES_EDMA3CHAN_PaRamStruct::srcFrameIndex

Source ccnt index.

Remarks:

Signed value specifying the byte address offset between frames within a block (3rd dimension).

Valid values range from -32768 to 32767 inclusive.

For A-synchronized transfers, the byte address offset from the beginning of the last source array in a frame to the beginning of the first source array in the next frame.

For AB-synchronized transfers, the byte address offset from the beginning of the first source array in a frame to the beginning of the first source array in the next frame.

unsigned short IRES_EDMA3CHAN_PaRamStruct::dstFrameIndex

Destination ccnt index.

Remarks:

Signed value specifying the byte address offset between frames within a block (3rd dimension).

Valid values range from -32768 to 32767 inclusive.

For A-synchronized transfers, the byte address offset from the beginning of the last destination array in a frame to the beginning of the first destination array in the next frame.

For AB-synchronized transfers, the byte address offset from the beginning of the first destination array in a frame to the beginning of the first destination array in the next frame.

unsigned short IRES_EDMA3CHAN_PaRamStruct::ccnt

Count for 3rd dimension

Remarks:

Unsigned value specifying the number of frames in a block, where a frame is bcnt arrays of acnt bytes.

Valid values range from 1 to 65535 inclusive.

unsigned short IRES_EDMA3CHAN_PaRamStruct::rsvd

Reserved.
