Yes, BUT... [I have never tried it]
The only way tat I know to do this reliably is to use ARDY to hold the
memory cycle. If you do this, the DSP will be stalled and if you have
dynamic memory, it will not be refreshed [causing memory problems].
You really should use a GPIO pin or external logic to accomplish this.
