Advance bit in the USBSTS register. If the Interrupt on Async Advance Enable bit in the USBINTR
register is set, the host controller issues a hardware interrupt at the next interrupt threshold. A detailed
explanation of this feature is described in
Schedule.”
24.9.14.2.4 Host System Error
The host controller is a bus master and any interaction between the host controller and the system may
experience errors. The type of host error may be catastrophic to the host controller making it impossible
for the host controller to continue in a coherent fashion. Behavior for these types of errors is to halt the
host controller. Host-based error must result in the following actions:

24.10 Device Data Structures
This section defines the interface data structures used to communicate control, status, and data between
Device Controller Driver (DCD) software and the Device Controller. The data structure definitions in this
chapter support a 32-bit memory buffer address space. The interface consists of device Queue Heads and
Transfer Descriptors.

The Run/Stop bit in the USBCMD register is cleared.
The Host System Error and HCHalted bits in the USBSTS register are set:
If the Host System Error Enable bit in the USBINTR register is set, then the host controller issues
a hardware interrupt. This interrupt is not delayed to the next interrupt threshold.
summarizes the required actions taken on the various host errors.

After a Host System Error, the software must reset the host controller using
HCReset in the USBCMD register before re-initializing and restarting the
host controller.
