42.8 UHPHS Periodic Frame List Base Address Register

This 32-bit register contains the beginning address of the Periodic Frame List in the system memory. The memory structure referenced by this physical memory pointer is assumed to be 4-Kbyte aligned. The contents of this register are combined with the Frame Index Register (UHPHS_FRINDEX) to enable the Host Controller to step through the Periodic Frame List in sequence. This register must be written as a DWord. Byte writes produce undefined results.
