I
When 16/68# pin is at logic 1, the Intel bus interface is selected and
this input becomes read strobe (active low). The falling edge insti-
gates an internal read cycle and retrieves the data byte from an
internal register pointed by the address lines [A2:A0], puts the data
byte on the data bus to allow the host processor to read it on the ris-
ing edge.
When 16/68# pin is at logic 0, the Motorola bus interface is selected
and this input is not used and should be connected to VCC.

I
When 16/68# pin is at logic 1, it selects Intel bus interface and this
input becomes write strobe (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.
When 16/68# pin is at logic 0, the Motorola bus interface is selected
and this input becomes read (logic 1) and write (logic 0) signal.

I
When 16/68# pin is at logic 1, this input is chip select A (active low)
to enable channel A in the device.
When 16/68# pin is at logic 0, this input becomes the chip select
(active low) for the Motorola bus interface.

When 16/68# pin is at logic 1, this input is chip select B (active low)
to enable channel B in the device.
When 16/68# pin is at logic 0, this input becomes address line A3
which is used for channel selection in the Motorola bus interface.

When 16/68# pin is at logic 1, this input is chip select C (active low)

When 16/68# pin is at logic 0, this input becomes address line A4
which is used for channel selection in the Motorola bus interface.

I
When 16/68# pin is at logic 1, this input is chip select D (active low)
to enable channel D in the device.
When 16/68# pin is at logic 0, this input is not used and should be
connected VCC.
