DSP1 WDMA Channel n 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.

DSP1 DMA Buffer Length

Selects the amount of data transferred in

each WDMA channel. The LSB represents

one 24-bit DSP memory word.

Note that this field must be set to 00h

when DSP1 is disabled.

DSP1 WDMA Channel Enable

There are 8 WDMA channels; each bit of

this field enables the respective WDMA

channel.

Each bit is coded as:

0 = Disabled

1 = Enabled

Note that this field must be set to 00h

when DSP1 is disabled.

DSP1 RDMA Channel Enable

There are 6 RDMA channels; each bit of

this field enables the respective RDMA

channel.

Each bit is coded as:

0 = Disabled

1 = Enabled

Note that this field must be set to 00h

when DSP1 is disabled.
