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
instigates 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 rising edge.
When 16/68# pin is at logic 0, the Motorola bus interface is
selected and this input is not used.

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. Motorola bus interface is not available on the 64 pin pack-
age.

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.
Motorola bus interface is not available on the 64 pin package.

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.
Motorola bus interface is not available on the 64 pin package.

I
When 16/68# pin is at logic 1, this input is chip select C (active low)
to enable channel C in the device.
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.
Motorola bus interface is not available on the 64 pin package.

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.
Motorola bus interface is not available on the 64 pin package.

When 16/68# pin is at logic 1 for Intel bus interface, this ouput
becomes channel A interrupt output. The output state is defined by
the user and through the software setting of MCR[3]. INTA is set to
the active mode when MCR[3] is set to a logic 1. INTA is set to the
three state mode when MCR[3] is set to a logic 0 (default). See
MCR[3].
When 16/68# pin is at logic 0 for Motorola bus interface, this output
becomes device interrupt output (active low, open drain). An exter-
nal pull-up resistor is required for proper operation.
Motorola bus interface is not available on the 64 pin package.
