Interrupt Latches
Two primary latches are associated with the interrupt structure:
•
•
A.
B.
C.
Interrupt Pending (IP). Set whenever the DMA requests an interrupt
but has not yet acknowledged. It holds the INT line Low (Figure 34).
Interrupt Under Service (IUS). Set when the CPU acknowledges the
DMA interrupt (Figure 35). This accomplishes three things:
–
Prevents further interrupts by this DMA
