There's a single ti-sysc interconnect target module, but it has multiple devices. There are two musb controler instances, two phy instances and a cppi41 dma instance within a single module. With sgx, I belive there is only the sgx IP within the ti-sysc interconnect target module. They are still seprate devices with their own control registers. Regards, Tony
