iomux0 is responsible for routing some functions to either the FPGA fabric,
|
|
or to MSSIOs. It only performs muxing, and has no IO configuration role, as
|
|
fabric IOs are configured separately and just routing a function to MSSIOs is
|
|
not sufficient for it to actually get mapped to an MSSIO, just makes it
|
|
possible.
