|
| 03.11.2020 | 1.4.6.6 | Removed SPI module's *buggy* "LSB-first mode", SPI module now always sends data MSB-first; removed SPI.CTRL `SPI_CT_DIR` bit; modfied bit order in SPI CTRL register; updated SPI SW library |
|
|
| 02.11.2020 | 1.4.6.5 | :warning: Fixed bug in CPU's illegal instruction detection logic; CPU rtl code optimizations - further reduced hardware footprint; rtl code clean-ups |
|
|
| 01.11.2020 | 1.4.6.4 | :warning: Fixed bug in `[m]instret[h]` and `[m]cycle[h]` carry logic; CPU hardware optimizations (area reduction, shortend critical path) |
|
|
| 29.10.2020 | 1.4.6.3 | rtl code clean-up; made preparations for additional co-processors |
|
|
| 25.10.2020 | 1.4.6.2 | Added tag signal (`wb_tag_o`) to processor's Wishbone bus; removed processors's `priv_o` - privilege level is now encoded in Wishbone *tag* signal; added a more sophisticated **FreeRTOS** example ("full_demo") |
|
| 24.10.2020 | [**:rocket:1.4.6.0**](https://github.com/stnolting/neorv32/releases/tag/v1.4.6.0) | Completely reworked external memory interface (WISHBONE), removed now-obsolete processor generic `MEM_EXT_REG_STAGES`; added processor wrapper with **AXI4-Lite master interface** |

|
| 22.10.2020 | 1.4.5.11 | TWI: Added new control register flag to enable/disable SCL clock stretching by peripheral devices |

|
| 22.10.2020 | 1.4.5.10 | Added `i_bus_priv_o` and `d_bus_priv_o` signals to CPU_top and `priv_o` to Processor_top to show privilege level of bus access (from `mstatus` MPP); :warning: Fixed bug in external memory interface [WISHBONE] (non-standard Wishbone components were able to corrupt processor-internal ACK/ERR signal logic) |
