 These are ``mvendorid``, ``marchid`` and ``mimpid``.
 The fixed, read-only values for these CSRs are defined in :file:`rtl/cve2_pkg.sv`.
 Implementers should carefully consider appropriate values for these registers.
-Ibex, as an open source implementation, has an assigned architecture ID (``marchid``) of 22.
+Ibex, as an open source implementation, has an assigned architecture ID (``marchid``) of of 0x23 (equivalent to 0d35).
 (Allocations are specified in `marchid.md of the riscv-isa-manual repository <https://github.com/riscv/riscv-isa-manual/blob/master/marchid.md>`_.)
 If significant changes are made to the micro-architecture a different architecture ID should be used.
-The vendor ID and implementation ID (``mvendorid`` and ``mimpid``) both read as 0 by default, meaning non-implemented.
-Implementers may wish to use other values here.
+The vendor ID and implementation ID (``mvendorid`` and ``mimpid``). The vendor ID (mvendorid) is assigned the value 0x602 and the implementation ID (mimpid) is assigned the value 0x0.
 Please see the RISC-V Privileged Architecture specification for more details on what these IDs represent and how they should be chosen.
