Description
Physical address of current ED on the control ED list
This field represents bits 31:4 of the physical address of the
next ED on the control ED list. EDs are assumed to begin at
16-byte-aligned address, so bits 3:0 of this pointer are
assumed to be 0. See Section 2.9, Physical Addressing, for
the restrictions on physical addresses.
A value of 0x0000000 indicates that the USB host controller
has reached the end of the control ED list without finding any
transfers to process.
This register is automatically updated by the USB host
controller.
Reserved
The head bulk register defines the physical address of the head ED on the bulk
ED list.
