READ HIT/WRITE HIT (WITHOUT CPU DBG PARKED)
is asserted in the same cycle that the processor asserts TS.
This implies CPU DBG is parked. In some systems it may not
be desirable or possible to park CPU DBG. Figure 9 shows

the response for a read hit from the MPC2605 is gated by the
assertion of CPU DBG. The fastest response possible in a
system that does not park CPU DBG is 3–1–1–1.
