16/68 Interface type select (input with internal pull-up).
This input provides the 16 (Intel) or 68 (Motorola) bus
interface type select. The functions of IOR, IOW,
INTA to INTD, and CSA to CSD are re-assigned with the
logical state of this pin. When this pin is a logic 1, the
16 mode interface (16C654) is selected. When this pin is a
logic 0, the 68 mode interface (68C654) is selected. When
this pin is a logic 0, IOW is re-assigned to R/W, RESET is
re-assigned to RESET, IOR is not used, and INTA to INTD
are connected in a wire-OR configuration. The wire-OR
outputs are connected internally to the open-drain IRQ
signal output. This pin is not available on 64-pin packages
which operate in the 16 mode only.
Address 0 select bit.
Internal registers address selection in
16 and 68 modes.
Address 1 select bit.
Internal registers address selection in
16 and 68 modes.
Address 2 select bit.
Internal registers address selection in
16 and 68 modes.
Address 3, Address 4 select bits.
When the 68 mode is
selected, these pins are used to address or select individual
UARTs (providing CS is a logic 0). In the 16 mode, these
pins are re-assigned as chip selects, see CSB and CSC.
These pins are not available on 64-pin packages which
operate in the 16 mode only.
Carrier Detect (active LOW).
These inputs are associated
with individual UART channels A through D. A logic 0 on this
pin indicates that a carrier has been detected by the modem
for that channel.

Clock Select.
The 1
×
or 4
×
pre-scalable clock is selected by
this pin. The 1
×
clock is selected when CLKSEL is a logic 1
(connected to V
CC
) or the 4
×
is selected when CLKSEL is a
logic 0 (connected to GND). MCR[7] can override the state
of this pin following reset or initialization (see MCR[7]). This
pin is not available on 64-pin packages which provide
MCR[7] selection only.
Chip Select (active LOW).
In the 68 mode, this pin
functions as a multiple channel chip enable. In this case, all
four UARTs (A to D) are enabled when the CS pin is a
logic 0. An individual UART channel is selected by the data
contents of address bits A[3:4]. when the 16 mode is
selected (68-pin devices), this pin functions as CSA (see
definition under CSA, CSB). This pin is not available on
64-pin packages which operate in the 16 mode only.
