10.1.4
HcInterruptStatus register (R/W: 03H/83H)
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
Section 10.1.5
) and bit MasterInterruptEnable is set. The HCD can clear
individual 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.

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.

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
μ
s. 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.
