HcInterruptDisable - Host Controller Interrupt Disable register bit description
11.1.7 HcHCCA register
Description
Master Interrupt Enable:
0 — Ignore
1 — Disables interrupt generation because of events specified in other bits of this register.
This field is set after a hardware or software reset. Interrupts are disabled.
Ownership Change:
0 — Ignore
1 — Disables interrupt generation because of ownership change.
-
Root Hub Status Change:
0 — Ignore
1 — Disables interrupt generation because of root hub status change.
Frame Number Overflow:
0 — Ignore
1 — Disables interrupt generation because of frame number overflow.
Unrecoverable Error:
0 — Ignore
1 — Disables interrupt generation because of unrecoverable error.
Resume Detect:
0 — Ignore
1 — Disables interrupt generation because of resume detect.
Start-of-Frame:
0 — Ignore
1 — Disables interrupt generation because of Start-of-Frame.
HcDoneHead Write-back:
0 — Ignore
1 — Disables interrupt generation because of HcDoneHead write-back.
Scheduling Overrun:
0 — Ignore
1 — Disables interrupt generation because of scheduling overrun.
The HcHCCA register contains the physical address of Host Controller Communication
Area (HCCA). The bit allocation is given in
restrictions by writing all 1s to HcHCCA and reading the content of HcHCCA. The
alignment is evaluated by examining the number of zeroes in lower order bits. The
minimum alignment is 256 bytes; therefore, bits 0 through 7 will always return logic 0
when read. This area is used to hold control structures and the interrupt table that are
accessed by both the Host Controller and the HCD.
