Address data lines [2:0]. These 3 address lines select one of the internal regis-
ters in UART channel A-D during a data bus transaction.

I
When 16/68# pin is HIGH, 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 LOW, the Motorola bus interface is selected and this input is
not used and should be connected to VCC.
IOW#
(R/W#)
9
18
I
When 16/68# pin is HIGH, 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 LOW, the Motorola bus interface is selected and this input
becomes read (HIGH) and write (LOW) signal.
CSA#
(CS#)
7
16
I
When 16/68# pin is HIGH, this input is chip select A (active low) to enable chan-
nel A in the device.
When 16/68# pin is LOW, this input becomes the chip select (active low) for the
Motorola bus interface.
CSB#
(A3)
11
20
I
When 16/68# pin is HIGH, this input is chip select B (active low) to enable chan-
nel B in the device.
When 16/68# pin is LOW, this input becomes address line A3 which is used for
channel selection in the Motorola bus interface.
CSC#
(A4)
38
50
I
When 16/68# pin is HIGH, this input is chip select C (active low) to enable chan-
nel C in the device.
When 16/68# pin is LOW, this input becomes address line A4 which is used for
channel selection in the Motorola bus interface.
CSD#
(VCC)
42
54
I
When 16/68# pin is HIGH, this input is chip select D (active low) to enable chan-
nel D in the device.
When 16/68# pin is LOW, this input is not used and should be connected VCC.
