When instruction tagging is on, a 0 at the falling edge of E tags the high half of the
instruction word being read into the instruction queue.
In expanded wide mode or emulation narrow modes, when instruction tagging is on
and low strobe is enabled, a 0 at the falling edge of E tags the low half of the
instruction word being read into the instruction queue.
