The {\tt mepc} register is written with the -address of the next instruction to be executed at the time the NMI was -taken, and {\tt mcause} is set to a value indicating the source of the +virtual address of the instruction that was interrupted, +and {\tt mcause} is set to a value indicating the source of the NMI. The NMI can thus overwrite state in an active machine-mode interrupt handler. |
