system software loads this register before starting the schedule execution by the Host
Controller. The memory structure referenced by this physical memory pointer is assumed
as 4 kB aligned. The contents of this register are combined with the FRINDEX register to
enable the Host Controller to step through the periodic frame list in sequence.
The bit allocation is given in
This 32-bit register 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 (bit 0 of
the HCCPARAMS register), the most significant 32 bits of every control data structure
address comes from the CTRLDSSEGMENT register. For details on the
CTRLDSSEGMENT register, refer to Enhanced Host Controller Interface Specification for
Universal Serial Bus Rev. 1.0 . Bits 4 to 0 of this register always return zeros when read.
The memory structure referenced by the physical memory pointer is assumed as 32 bytes
(cache aligned). For bit allocation, see
Description
Base Address: These bits correspond to memory address signals 31 to 12, respectively.
