Table 13.
This register provides the status of the events that cause hardware interrupts. When an
event occurs, the HC sets the corresponding bit in this register. When a bit is set, a
hardware interrupt is generated if the interrupt is enabled in the HcInterruptEnable register
(see
bits in this register by writing logic 1 to the bit positions to be cleared, but cannot set any of
these bits. Conversely, the HC can set bits in this register, but cannot clear these bits.

Description
reserved
SchedulingOverrunCount: The field is incremented on each
scheduling overrun error. It is initialized to 00B and wraps around at
11B. It will be incremented when a scheduling overrun is detected
even if SchedulingOverrun in HcInterruptStatus has already been set.
This is used by HCD to monitor any persistent scheduling problems.
reserved
HostControllerReset: This bit is set by the HCD to initiate a software
reset of the HC. Regardless of the functional state of the HC, it moves
to the USBSuspend state in which most of the operational registers
are reset, except those stated otherwise, and no Host bus accesses
are allowed. This bit is cleared by the HC upon the completion of the
reset operation. The reset operation must be completed within 10 μs.
This bit, when set, does not cause a reset to the Root Hub and no
subsequent reset signaling should be asserted to its downstream
ports.
