I
UART channel A Receive Data or infrared receive data.
Normal receive data input must idle at logic 1 condition.
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] and FCTR[2]. If this pin is not used,
tie it to VCC or pull it high via a 100k ohm resistor.

O
UART channel A or B 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],
FCTR[1:0], EMSR[5:4] and IER[6].

I
UART channel A or B Clear-to-Send (active low) or gen-
eral purpose input. It can be used for auto CTS flow con-
trol, see EFR[7], and IER[7]. This input should be
connected to VCC when not used.

O
Output Port 2 channel A or B - The output state is defined
by the user and through the software setting of MCR[3].
INTA or INTB is set to the active mode and OP2A# or
OP2B# output to a logic 0 when MCR[3] is set to a logic
1. INTA or INTB is set to the three state mode and OP2A#
or OP2B# 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 or INTB output function-
ality.

I
RS-485 half duplex directional control for channel A and B
(active low). Connect to VCC for normal RTS# function
and connect to GND for RS-485 half duplex direction con-
trol. RTS# pin goes low for transmit and high for receive.
This pin is wire “OR-ed” with FCTR[3]. See FCTR[3].
