When instruction tagging is on, tags the high half of the instruction word being
read into the instruction queue.
When instruction tagging is on, tags the low half of the instruction word being
read into the instruction queue.
In emulation modes, a low assertion on this pin in the 7th or 8th cycle after the
end of reset enables the Unconditional Tagging function.
