Description
Root Hub Status Change:
0 — Ignore
1 — Enables interrupt generation because of root hub status change.
Frame Number Overflow:
0 — Ignore
1 — Enables interrupt generation because of frame number overflow.
Unrecoverable Error:
0 — Ignore
1 — Enables interrupt generation because of unrecoverable error.
Resume Detect:
0 — Ignore
1 — Enables interrupt generation because of resume detect.
Start-of-Frame:
0 — Ignore
1 — Enables interrupt generation because of Start-of-Frame.
HcDoneHead Write-back:
0 — Ignore
1 — Enables interrupt generation because of HcDoneHead write-back.
Scheduling Overrun:
0 — Ignore
1 — Enables interrupt generation because of scheduling overrun.
Each disable bit in the HcInterruptDisable register corresponds to an associated interrupt
bit in the HcInterruptStatus register. The HcInterruptDisable register is coupled with the
HcInterruptEnable register. Therefore, writing logic 1 to a bit in this register clears the
corresponding bit in the HcInterruptEnable register, whereas writing logic 0 to a bit in this
register leaves the corresponding bit in the HcInterruptEnable register unchanged. On a
read, the current value of the HcInterruptEnable register is returned.
The register contains 4 bytes, and the bit allocation is given in
