Appendix C: TS-7390 FGPA Register Map
By default the Lattice FPGA on the TS-7390 is loaded with a system
controller
core at base physical address 0x600F_F080. Add that base to the offsets
below
to access these registers. These registers are all 16 bits wide and
should
therefore be accessed with 16 bit writes.
base + 0x06:
bit 06: 485 Full Duplex Control
So just modify that many mmap bit fiddling examples you can find around and
you're probably done.
