I
Chip select (active LOW). A LOW at this pin enables the parallel port /
CPU data transfer operation.
IOCHRDY

O
I/O Channel ready (internal pull-up / three stated active HIGH). This pin
goes low when the device requires addition clock cycles for read and
write.

I
DMA address enable (active HIGH). When this line is HIGH, the DMA
controller has control of the address bus.

O
Active high AT bus DMA ReQuest for channels 3, 2 and 1 (internal pull-
down three stated active HIGH). A request is generated by bringing a
DRQx line to a HIGH level. A DRQx line is held HIGH until the corre-
sponding DMA acknowledge “DACKx*” line goes LOW.
-DACK3

DMA Acknowledge signals for channels 3, 2 and 1 (internal pull-up /three
stated active low).
TC

I
Terminal Count (active HIGH). The ST78C36 terminates the DMA channel
when a HIGH pulse is detected.
