CHIP: LPC11u6x DMA Controller driver common functions
[CHIP: LPC11u6x DMA Controller driver]

De-Initialize DMA controller.

Parameters:

pDMA	: The base of DMA controller on the chip

Returns:

Nothing

Definition at line 125 of file dma_11u6x.h.

Disable DMA controller.

Parameters:

pDMA	: The base of DMA controller on the chip

Returns:

Nothing

Definition at line 146 of file dma_11u6x.h.

Enable DMA controller.

Parameters:

pDMA	: The base of DMA controller on the chip

Returns:

Nothing

Definition at line 136 of file dma_11u6x.h.

Get pending interrupt or error interrupts.

Parameters:

pDMA	: The base of DMA controller on the chip

Returns:

An Or'ed value of DMA_INTSTAT_* types

Note:

If any DMA channels have an active interrupt or error interrupt pending, this functional will a common status that applies to all channels.

Definition at line 163 of file dma_11u6x.h.

Returns DMA controller SRAM base address.

Parameters:

pDMA	: The base of DMA controller on the chip

Returns:

The base address where the DMA descriptors are stored

Definition at line 196 of file dma_11u6x.h.

Initialize DMA controller.

Parameters:

pDMA	: The base of DMA controller on the chip

Returns:

Nothing

Definition at line 114 of file dma_11u6x.h.

Set DMA controller SRAM base address.

Parameters:

pDMA	: The base of DMA controller on the chip
base	: The base address where the DMA descriptors will be stored

Returns:

Nothing

Note:

A 256 byte block of memory aligned on a 256 byte boundary must be provided for this function. It sets the base address used for DMA descriptor table (16 descriptors total that use 16 bytes each).

A pre-defined table with correct alignment can be used for this function by calling Chip_DMA_SetSRAMBase(LPC_DMA, DMA_ADDR(Chip_DMA_Table));
