Power State — R/W. This 2-bit field is used both to determine the current power state
of EHC function and to set a new power state. The definition of the field values are:
00 = D0 state
11 = D3
If software attempts to write a value of 10b or 01b in to this field, the write operation
must complete normally; however, the data is discarded and no state change occurs.
When in the D3
range; but the configuration space must still be accessible. When not in the D0 state,
the generation of the interrupt output is blocked. Specifically, the PIRQH is not asserted
by the ICH7 when not in the D0 state.
When software changes this value from the D3
warm (soft) reset is generated, and software must re-initialize the function.
Debug Port Capability ID — RO. Hardwired to 0Ah indicating that this is the start of a
Debug Port Capability structure.
Next Item Pointer 2 Capability — RO. Hardwired to 00h to indicate there are no more
capability structures in this function.
BAR Number — RO. Hardwired to 001b to indicate the memory BAR begins at offset
10h in the EHCI configuration space.
Debug Port Offset — RO. Hardwired to 0A0h to indicate that the Debug Port registers
begin at offset A0h in the EHCI memory range.
