MOTOROLA
When HALT is asserted and BERR is not asserted, the MC68030 halts external
timing requirements provides a single-step (bus cycle to bus cycle) operation.
The HALT signal affects external bus cycles only; thus, a program that resides
the data cache) may continue executing, unaffected by the HALT signal.
a bus cycle. Negating and reasserting HALT in accordance with the correct
in the instruction cache and performs no data writes (or reads that miss in
bus activity at the next bus cycle boundary. HALT by itself does not terminate
