2.97V TO 5.5V QUAD UART WITH 128-BYTE FIFO
REV. 2.2.0
CSC#
(A4)
64
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 chan-
nel selection in the Motorola bus interface.
CSD#
(N.C.)
68
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.
INTA
(IRQ#)
12
O
(OD)
When 16/68# pin is at logic 1 for Intel bus interface, this ouput becomes channel A inter-
rupt 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 inter-
rupt output (active low, open drain). An external pull-up resistor is required for proper
operation.
INTB
INTC
INTD
(N.C.)

69
O
When 16/68# pin is at logic 1 for Intel bus interface, these ouputs become the interrupt
outputs for channels B, C, and D. The output state is defined by the user through the soft-
ware setting of MCR[3]. The interrupt outputs are set to the active mode when MCR[3] is
set to a logic 1 and are 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, these outputs are unused and
will stay at logic zero level. Leave these outputs unconnected.
INTSEL
87
I
Interrupt Select (active high, input with internal pull-down).
When 16/68# pin is at logic 1 for Intel bus interface, this pin can be used in conjunction
with MCR bit-3 to enable or disable the INT A-D pins or override MCR bit-3 and enable
the interrupt outputs. Interrupt outputs are enabled continuously by making this pin a
logic 1. Making this pin a logic 0 allows MCR bit-3 to enable and disable the interrupt out-
put pins. In this mode, MCR bit-3 is set to a logic 1 to enable the continuous output. See
MCR bit-3 description for full detail. This pin must be at logic 0 in the Motorola bus inter-
face mode.

O
UART channels A-D Transmitter Ready (active low). These outputs provide the TX FIFO/
THR status for transmit channels A-D. See
Table 5. If Direct Memory Access is enabled,
these outputs become Transmit Direct Memory Access Request outputs. See TXDRQ pin
description for more details. If these outputs are unused, leave them unconnected.

O
UART channels A-D Receiver Ready (active low). These outputs provide the RX FIFO/
RHR status for receive channels A-D. See
Table 5. If Direct Memory Access is enabled,
these outputs become Receive Direct Memory Access Request outputs. See RXDRQ pin
description for more details. If these outputs are unused, leave them unconnected.
TXRDY#
45
O
Transmitter Ready (active low). This output is a logically wire-ORed status of TXRDY#
A-D. See
Table 5. If this output is unused, leave it unconnected.
RXRDY#
44
O
Receiver Ready (active low). This output is a logically wire-ORed status of RXRDY# A-D.
See
Table 5. If this output is unused, leave it unconnected.
