16.3.2.5
The CTRLDSSEGMENT register is not implemented on the MPC8313E.
16.3.2.6
This register contains the beginning address of the Periodic Frame List in the system memory. The host
controller driver loads this register prior to starting the schedule execution by the controller. 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 (FRINDEX) to enable the controller to step
through the Periodic Frame List in sequence.

Reserved, should be cleared.
Bits N–3 are used for the Frame List current index. This means that each location of the frame list is
accessed 8 times (frames or microframes) before moving to the next index.
In device mode, the value is the current frame number of the last frame transmitted. It is not used as an
index.
In either mode, bits 2–0 indicate the current microframe.
