Cyclone V Transceiver Reconfiguration Settings Available When Streaming mif Files

I am using a Cyclone V with the Native PHY IP transceiver.

I need to be able to set a bunch of different transceiver settings to different values during runtime for a design I'm doing. According to the transceiver user guide (UG-01080), I only have a limited set of settings that I can manipulate using the register based reconfiguration management interface. For example, I can change the CMU PLL refclk input using this interface, but not the CMU PLL multiplier value.

What settings would be available to me if I used the streamer interface and mif files? Can I completely change ALL of the transceiver settings if I stream mif files from compiled transceiver designs, or is there only a subset that I can change like with the register based interface?

Thanks for your help!

    From memory I think you are limited to what you can reconfigure through a streaming MIF as my C5 transceiver design uses both Avalon MM register writes for loopback modes and a streaming MIF for speed changes i.e. Tx local divider and Rx reference dividers.
