24.6.3.7
Device Address Register (DEVICEADDR), Non-EHCI
This register is not defined in the EHCI specification. The upper seven bits of this register represent the
device address. After any controller reset or a USB reset, the device address is set to the default address
(0). The default address will match all incoming addresses. The software shall reprogram the address after
receiving a SET_ADDRESS descriptor.
This register is shared between the host and device mode functions. In device mode, it is the
DEVICEADDR register; in host mode, it is the PERIODICLISTBASE register. See
“Periodic Frame List Base Address Register (PERIODICLISTBASE),”
for more information.
24.6.3.8
Current Asynchronous List Address Register (ASYNCLISTADDR)
This 32-bit register contains the address of the next asynchronous queue head to be executed by the host.
Bits [4–0] of this register cannot be modified by the system software and always return zeros when read.
Note that on the USB OTG module, this register is shared between the host and device mode functions. In
host mode, it is the ASYNCLISTADDR register; in device mode, it is the ENDPOINTLISTADDR
register. See
Section 24.6.3.9, “Endpoint List Address Register (ENDPOINTLISTADDR), Non-EHCI,”
for more information.
