O
UART channel B Transmitter Ready (active low). The out-
put provides the TX FIFO/THR status for transmit channel
B. If it is not used, leave it unconnected.
RXRDYB#

18
O
UART channel B Receiver Ready (active low). This output
provides the RX FIFO/RHR status for receive channel B.
If it is not used, leave it unconnected.

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

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#

33
O
UART channel A Request-to-Send (active low) or general
purpose output. This output must be asserted prior to
using auto RTS flow control, see EFR[6], MCR[1] and
IER[6]. If it is not used, leave it unconnected.
CTSA#
25
40
38
I
UART channel A Clear-to-Send (active low) or general
purpose input. It can be used for auto CTS flow control,
see EFR[7] and IER[7]. This input should be connected to
VCC when not used.
DTRA#

O
UART channel A Data-Terminal-Ready (active low) or
general purpose output. If it is not used, leave it uncon-
nected.
DSRA#
-
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#
-
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#
-
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#

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. This output should not be used as a gen-
eral output else it will disturb the INTA output functionality.
If it is not used at all, leave it unconnected.
