* Optional hardware performance monitors (HPM) for application benchmarking
* Separated interfaces for instruction fetch and data access (merged into single bus via a bus switch for
the NEORV32 processor)
* BIG-endian byte order
* little-endian byte order
* Configurable hardware reset
* No hardware support of unaligned data/instruction accesses – they will trigger an exception. If the C extension is enabled instructions
can also be 16-bit aligned and a misaligned instruction address exception is not possible anymore

This list shows the currently known issues regarding full RISC-V-compatibility. More specific information
can be found in section <<_instruction_sets_and_extensions>>.

[IMPORTANT]
CPU and Processor are BIG-ENDIAN, but this should be no problem as the external memory bus
interface provides big- and little-endian configurations. See section <<_processor_external_memory_interface_wishbone_axi4_lite>> for more information.

[IMPORTANT]
The `misa` CSR is read-only. It shows the synthesized CPU extensions. Hence, all implemented
CPU extensions are always active and cannot be enabled/disabled dynamically during runtime. Any
