addressed and written by the DMA controller. A write by the host during UDMA
data-out operation will erroneously interfere with the UDMA state machine.
Any read will return zero.
IDEDD:
0x800A_0024 - Read Only (should be read by the DMA controller only)
0x0000_0000
In UDMA data-in operations, this register contains the data at the head of the
input buffer to be transferred by the DMA controller. The data is read from this
register by the DMA controller. This register should only be addressed and
read by the DMA controller. A read by the host during UDMA data-in operation
will erroneously interfere with the UDMA state machine. Any write is ignored.
