FRINDEX register (R/W: 002Ch)
The Frame Index (FRINDEX) register is used by the Host Controller to index into the
periodic frame list. The register updates every 125
μ
s (once each microframe). Bits n to 3
are used to select a particular entry in the Periodic Frame List during periodic schedule
execution. The number of bits used for the index depends on the size of the frame list as
set by the system software in the FLS (Frame List Size) field of the USBCMD register.
This register must be written as a Double Word. A Word-only write (16-bit mode) produces
undefined results. This register cannot be written unless the Host Controller is in the
halted state as indicated by the HCH (HCHalted) bit. A write to this register while the RS
(Run/Stop) bit is set produces undefined results. Writes to this register also affect the SOF
value. The bit allocation is given in
Table 18

Frame List Rollover Enable
: When this bit is set and the FLR bit in the
USBSTS register is set, the Host Controller issues an interrupt. The
interrupt is acknowledged by software clearing bit FLR.
PCIE
Port Change Interrupt Enable
: When this bit is set and the PCD bit in the
USBSTS register is set, the Host Controller issues an interrupt. The
interrupt is acknowledged by software clearing bit PCD.
