I
Input/Output Read (active low). The falling edge instigates an internal read cycle
and retrieves the data byte from an internal register pointed by the address lines
[A2:A0], places it on the data bus to allow the host processor to read it on the lead-
ing edge. Either an active IOR# or IOR is required to transfer data from 850 to CPU
during a read operation. If not used, connect this pin to VCC. Caution: SEE”FAC-

I
Input/Output Read (active high). Same as IOR# but active high. Either an active
IOR# or IOR is required to transfer data from 850 to CPU during a read operation.
If not used, connect this pin to GND. During PC Mode, this pin becomes A3. Cau-

I
Input/Output Write (active low). The falling edge instigates the internal write cycle
and the rising edge transfers the data byte on the data bus to an internal register
pointed by the address lines [A2:A0]. Either an active IOW# or IOW is required to
transfer data from 850 to the Intel type CPU during a write operation. If not used,
connect this pin to VCC. Caution: SEE”FACTORY TEST MODE” ON PAGE 7.

I
Input/Output Write (active high). The rising edge instigates the internal write cycle
and the falling edge transfers the data byte on the data bus to an internal register
pointed by the address lines [A2:A0]. Either an active IOW# or IOW is required to
transfer data from 850 to the Intel type CPU during a write operation. During PC
Mode, this pin becomes A8. If not used, connect this pin to GND. Caution:
