| 30.10.2021 | 1.6.2.12 | :sparkles: :lock: added memory-mapped register to BUSKEEPER module - software can now retrieve the actual cause of an instruction / data-load / data-store bus access fault exception (access timeout or device error); see [PR #191](https://github.com/stnolting/neorv32/pull/191) |
