HS USB PCI Host Controller
11.4.7 ASYNCLISTADDR register (address: content of the base address register +
24h)
This 32-bit register (bit allocation: Table 114) contains the address of the next
asynchronous queue head to be executed. If the Host Controller is in 64-bit mode, as
indicated by logic 1 in 64AC (64-bit Addressing Capability) eld in the HCCPARAMS
register, the most signicant 32 bits of every control data structure address comes from
the CTRLDSSEGMENT register. Bits 4 to 0 of this register always return zeros when read.
The memory structure referenced by the physical memory pointer is assumed to be
32 bytes (cache aligned).
