  • "The NEORV32 does not implement the user-mode time[h] registers. Any access to these registers will trap. It is recommended that the trap handler software provides a means of accessing the platform-defined MTIME machine timer." - same concept is used in Ibex/openTitan 😉
  • VHDL code cleanups
  • minor logic optimizations
  • fix minor bug in NEORV32 runtime environment: do not try to load the trap-causing instruction word when a instruction access fault exception has been raised
