DSPn_WDMA_ACTIVE_CH

ANNELS [7:0]

00h

DSPn WDMA Channel Status

There are 8 WDMA channels; each

bit of this field indicates the status of

the respective WDMA channel.

Each bit is coded as:

0 = Inactive

1 = Active

base address +10h

DSPn_WDMA_Buffer_1

31:16

DSPn_START_ADDRESS_

WDMA_BUFFER_1 [15:0]

0000h

DSPn WDMA Channel 1 Start

Address

Bit [15] = Memory select

0 = X Data memory

1 = Y Data memory

Bits [14:0] = Address select

The address is defined relative to the

base address of the applicable data

memory. The LSB represents one 24-

bit DSP memory word.

Note that the start address is also

controlled by the respective

DSPn_WDMA_CHANNEL_OFFSET

bit.

Bit [15] = Memory select

0 = X Data memory

1 = Y Data memory

Bits [14:0] = Address select

The address is defined relative to the

base address of the applicable data

memory. The LSB represents one 24-

bit DSP memory word.

Note that the start address is also

controlled by the respective

DSPn_RDMA_CHANNEL_OFFSET

bit.
