24.2.4
HcInterruptStatus Register (H'0400040C)
This register indicates the status in various events that cause hardware interrupts. When an event
occurs, the host controller sets the corresponding bit in this register. When the bit is set to 1, a
hardware interrupt is generated while an interrupt is enabled and the MsterInterrupEnable bit is set
in the HcInterruptEnable register (see section 24.2.5, HcInterruptEnable). The host control driver
clears a specified bit in this register by writing 1 in the bit position to be cleared. The host
controller driver cannot set any bit of these bits. The host controller never clears bits.

Description
Reserved.
OwnershipChange (OC)
This bit is set by the host controller when the
OwnershipChangeRequest bit in the HcCommandStatus
reigster is set. This event generates a system management
interrupt at once when not masked.
When there is no SMI pin, this bit is set to 0.
0: The OCR bit in the HcCommandStatus register is not set.
1: The OCR bit in the HcCommandStatus register is set.
Reserved.
RootHubStatusChange (RHSC)
This bit is set when the content of HcRhStatus or the content of
any HcRhPortStatus 1, 2 register [Number of Downstream Port]
has changed.
0: The content of the HcRhStatus register or HcRhPortStatus
1: The content of the HcRhStatus register or HcRhPortStatus
FrameNumberOverflow (FNO)
This bit is set when MSB (bit 15) in the HcFumnumber register
changes value from 0 to 1 or from 1 to 0 or the
HccaFrameNumber bit is updated.
0: MSB or the HccaFrameNumber bit in the HcFmNumber
1: MSB or the HccaFrameNumber bit in the HcFmNumber
