Description
-
Interrupt Threshold Control: Default = 08h. This field is used by the system software to select the
maximum rate at which the Host Controller will issue interrupts. If software writes an invalid value to
this register, the results are undefined. Valid values are:
00h — reserved
01h — 1 microframe
02h — 2 microframes
04h — 4 microframes
08h — 8 microframes (equals 1 ms)
10h — 16 microframes (equals 2 ms)
20h — 32 microframes (equals 4 ms)
40h — 64 microframes (equals 8 ms)
Software modifications to this field while HCH (bit 12) in the USBSTS register is zero results in
undefined behavior.
-
Light Host Controller Reset: This control bit is not required. It allows the driver software to reset
the EHCI controller, without affecting the state of the ports or the relationship to the companion Host
Controllers. If not implemented, a read of this field will always return zero. If implemented, on read:
0 — Indicates that the Light Host Controller Reset has completed and it is ready for the host
software to re-initialize the Host Controller.
1 — Indicates that the Light Host Controller Reset has not yet completed.
