EOT

10

5

I

End-Of-Transfer input (programmable

polarity, see Table 21); used by the DMA

controller to force the end of a DMA transfer

to the ISP1181B

DREQ

11

6

O

DMA request output (4 mA; programmable

polarity, see Table 21); signals to the DMA

controller that the ISP1181B wants to start

a DMA transfer

DACK

12

7

I

DMA acknowledge input (programmable

polarity, see Table 21); used by the DMA

controller to signal the start of a DMA

transfer requested by the ISP1181B
