pub type PROGRAMMABLE_FRAME_LIST_FLAG_R = BitReader<bool>;

Field programmable_frame_list_flag reader - Programmable Frame List Flag

If this bit is set to a zero, then system software must use a frame list length of 1024 elements with this host controller. The USBCMD register Frame List Size field is a read-only register and should be set to zero.

If set to 1, then system software can specify and use the frame list in the USBCMD register Frame List Size field to cofigure the host controller.

The frame list must always aligned on a 4K page boundary. This requirement ensures that the frame list is always physically contiguous.
