1 - Set or Clear the RWOP bit to configure for a Write or Read operation.
2 - Perform a dummy read of the IDEUDMAOp register.
3 - Set the UEN bit to enable UDMA operation.

In PIO mode write operation, this register is the Output Data Registers,
containing the register contents or the data to be written to the device. The
register is driven onto the DD pins when DIOWn is low. The register is both
read write in this operation. In MDMA and UDMA data-out operations, this
register is an exact copy of the data in the output buffer to be transferred to the
device. The register should only be read in these operations for checking the
output data. Any write in these two operation modes is ignored.

Reserved. Unknown during read, ignored during write.
Read or write operation selection:
0 - Read
1 - Write.
Enable Ultra DMA operation.
1 - to start UDMA
0 - to terminate UDMA by the host.
IDE output data in PIO writes (read write), data in output
buffer in MDMA and data at the tail of output buffer in
UDMA mode (read only).
