flushi rA
flushi r6
Ignoring the tag, flushi identifies the instruction cache line associated with the byte address
in rA, and invalidates that line.
If the Nios II processor core does not have an instruction cache, the flushi instruction
performs no operation.
For more information about the data cache, refer to the
chapter of the Nios II Software Developer’s Handbook.
