Host Interface (HDI08)
Servicing The Host Interface
•
The enabled request is cleared or masked
•
The DSP is reset.
If the host processor is a member of the MC68000 family, there is no need for the additional
step when the host processor reads the ISR to determine how to respond to an interrupt
generated by the DSP. Instead, the DSP automatically sources the contents of the IVR on the
data bus when the host processor acknowledges the interrupt by asserting HACK. The
contents of the IVR are placed on the host data bus while HOREQ and HACK are
simultaneously asserted. The IVR data tells the MC680XX host processor which interrupt
routine to execute to service the DSP.
