Without the new variant for mnxti to allow equal pil pending interrupt, pil in mcause needs to be reduced by 1. fortunately mcause is in a0 when csrrsi a1,mnxti,1 would...

Expressing concepts and issues in alternate terms can be useful and instructive. I believe @aswaterman has done an excellent job in guiding this effort. He has weighed representations with wisdom....
