Hello,

In section 61.5 of the [GRLIB IP Core User’s Manual](https://download.gaisler.com/products/GRLIB/doc/grip.pdf) there seems to be an error (GRIOMMU2 - AHB/AHB bridge with RISC-V IOMMU & IOPMP capabilities - Registers). The Interrupt-cause-to-vector register (icvec) is first listed to be in the address offset 0x02F8 - 0x02FC, but then in the detailed description (61.5.21) is listed at 0x0270-0x0274.

Also, the Translation-request control register (61.5.19) has bits overlapping in the description and some missing (bits 12-14). The DID description is missing and the bits 60-63 are not documented.

Best regards,

G. V. S.

Hello,

Thank you for bringing these documentation issues to light. They have now been fixed and will be included the next time we regenerate the GRLIB IP Core User’s Manual PDF.

Best regards,
