I
UART channel A Receive Data or infrared receive data.
Normal receive data input must idle HIGH. The infrared
receiver pulses typically idles at LOW but can be inverted
by software control prior going in to the decoder, see
MCR[6]. If this pin is not used, tie it to VCC or pull it high
via a 100k ohm resistor.
RTSA#

D5
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] and IER[6]. For
auto RS485 half-duplex direction control, see DLD[6].
CTSA#

A5
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 or GND when not used.

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

B6
I
UART channel A Data-Set-Ready (active low) or general
purpose input. This input should be connected to VCC or
GND when not used.

C5
I
UART channel A Carrier-Detect (active low) or general
purpose input. This input should be connected to VCC or
GND when not used.

A4
I
UART channel A Ring-Indicator (active low) or general
purpose input. This input should be connected to VCC or
GND when not used.

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 LOW
when MCR[3] is set to a logic 1. INTA is set to the three
state mode and OP2A# output HIGH when MCR[3] is set
to a logic 0. See MCR[3]. If INTA is used, this output
should not be used as a general output else it will disturb
the INTA output functionality.

D1
O
UART channel B Transmit Data or infrared encoder data.
Standard transmit and receive interface is enabled when
MCR[6] = 0. In this mode, the TX signal will be HIGH dur-
ing reset or idle (no data). Infrared IrDA transmit and
receive interface is enabled when MCR[6] = 1. In the
Infrared mode, the inactive state (no data) for the Infrared
encoder/decoder interface is LOW. If it is not used, leave
it unconnected.

I
UART channel B Receive Data or infrared receive data.
Normal receive data input must idle HIGH. The infrared
receiver pulses typically idles at logic 0 but can be
inverted by software control prior going in to the decoder,
see MCR[6]. If this pin is not used, tie it to VCC or pull it
high via a 100k ohm resistor.
