Description
Enable Write DMA PCI FIFO Overrun Attention.
Enable Write DMA PCI Host Address Overflow
Error Attention.
Enable Write DMA PCI Parity Error Attention.
Enable Write DMA PCI Master Abort Attention.
Enable Write DMA PCI Target Abort Attention.
This bit controls whether the Write DMA state
machine is active or not. When set to 0, it
completes the current operation and cleanly
halts. Until it is completely halted, it remains 1
when read.
When this bit is set to 1, the Write DMA state
machine is reset. This is a self-clearing bit.

longer than DMA length).
Write DMA PCI FIFO Underrun Error.
Write DMA PCI FIFO Overrun Error.
Write DMA PCI Host Address Overflow Error.
Write DMA PCI Parity Error.
