Functional Description
The Instruction Cache Flush instruction causes the instruction cache to
invalidate a specific line in the cache. The contents of the P-register spec-
ify the line to invalidate. The instruction cache contains no dirty bit.
Consequently, the contents of the instruction cache are never flushed to
higher levels.
This instruction does not cause address exception violations. If a protec-
tion violation associated with the address occurs, the instruction acts as a
and does not cause a protection violation exception.
NOP
Options
The instruction can post-increment the line pointer by the cache line size.
