+==== Xh3irq
+
+Xh3irq extension (as implemented by hazard3) <<hazard3>> provides nested and vectored
+interrupt handling that is conceptually similar to CLIC (`mnxti`) trampoline.
+
+Unlike CLIC, dispatcher has to index pointer array in software (by using index from `meinext`)
+
+Example handler implements only jumptable but it can be easily convertod into pointer table.
+
+Access to configuration bits of all 512 inputs is performed by inline windowing of configuration 
+CSRs, which is incompatible with zicsrind.
