2.97V TO 5.5V DUART WITH 16-BYTE FIFO
TXRDYB#
-

O
UART channel B Transmitter Ready (active low). The out-
put provides the TX FIFO/THR status for transmit channel
B. See Table 2. If it is not used, leave it unconnected.
RXRDYB#
-
23
18
O
UART channel B Receiver Ready (active low). This out-
put provides the RX FIFO/RHR status for receive channel
B. See Table 2. If it is not used, leave it unconnected.

O
UART channel A Transmit Data. If it is not used, leave it
unconnected.
RXA

11
5
I
UART channel A Receive Data. Normal receive data
input must idle at logic 1 condition. If it is not used, tie it to
VCC or pull it high via a 100k ohm resistor.
RTSA#

O
UART channel A Request-to-Send (active low) or general
purpose output. If it is not used, leave it unconnected.
CTSA#
36
40
38
I
UART channel A Clear-to-Send (active low) or general
purpose input. This input should be connected to VCC
when not used. This input has no effect on the UART.
DTRA#
33
37
34
O
UART channel A Data-Terminal-Ready (active low) or
general purpose output. If it is not used, leave it uncon-
nected.
DSRA#
37
41
39
I
UART channel A Data-Set-Ready (active low) or general
purpose input. This input should be connected to VCC
when not used. This input has no effect on the UART.
CDA#
38
42
40
I
UART channel A Carrier-Detect (active low) or general
purpose input. This input should be connected to VCC
when not used. This input has no effect on the UART.
RIA#
39
43
41
I
UART channel A Ring-Indicator (active low) or general
purpose input. This input should be connected to VCC
when not used. This input has no effect on the UART.
OP2A#
31

32
O
Output Port 2 Channel A - The output state is defined by
the user and through the software setting of MCR[3].
INTA is set to the active mode and OP2A# output to a
logic 0 when MCR[3] is set to a logic 1. INTA is set to the
three state mode and OP2A# to a logic 1 when MCR[3] is
set to a logic 0. See MCR[3]. This output should not be
used as a general output else it will disturb the INTA out-
put functionality. If it is not used at all, leave it uncon-
nected.
TXB

O
UART channel B Transmit Data. If it is not used, leave it

I
UART channel B Receive Data. Normal receive data
input must idle at logic 1 condition. If it is not used, tie it to
VCC or pull it high via a 100k ohm resistor.
