DTR0#
54
O
UART channel 0 Data Terminal Ready or general purpose output (active low).
This port must be asserted prior using for one of two functions:
1) auto DTR flow control, see EFR bit-6, FCTR bits-0 to 3, MCR bits-0 & 2,
and IER bit-6
2) Auto RS485 half-duplex direction control, see FCTR bit-5, MCR bit-2 and
MSR bit 4-7.
DSR0#
58
I
UART channel 0 Data Set Ready or general purpose input (active low). It can
be used for auto DSR flow control, see EFR bit-7, MCR bit-2 and IER bit-7.
CD0#
57
I
UART channel 0 Carrier Detect or general purpose input (active low).
RI0#
56
I
UART channel 0 Ring Indicator or general purpose input (active low).
TX1
48
O
UART channel 1 Transmit Data or infrared transmit data. Normal TXD output
idles HIGH while infrared TXD output idles LOW.
UART channel 1 Receive Data or infrared receive data. Normal RXD input
idles HIGH while infrared RXD input idles LOW. In the infrared mode, the
polarity of the incoming RXD signal can be selected via FCTR bit-4. If this bit
is a logic 0, a LOW on the RXD input is considered a mark and if this bit is a
logic 1, a HIGH on the RXD input is considered a space.

I
RTS1#
46
O
UART channel 1 Request to Send or general purpose output (active low).
See description of RTS0# pin.
CTS1#
42
I
UART channel 1 Clear to Send or general purpose input (active low). See
description of CTS0# pin.
DTR1#
47
O
UART channel 1 Data Terminal Ready or general purpose output (active low).
See description of DTS0# pin.
DSR1#
43
I
UART channel 1 Data Set Ready or general purpose input (active low). See
description of DSR0# pin.
CD1#
44
I
UART channel 1 Carrier Detect or general purpose input (active low).
RI1#
45
I
UART channel 1 Ring Indicator or general purpose input (active low).
TX2
40
O
UART channel 2 Transmit Data or infrared transmit data. Normal TXD output
idles HIGH while infrared TXD output idles LOW.
UART channel 2 Receive Data or infrared receive data. Normal RXD input
idles HIGH while infrared RXD input idles LOW. In the infrared mode, the
polarity of the incoming RXD signal can be selected via FCTR bit-4. If this bit
is a logic 0, a LOW on the RXD input is considered a mark and if this bit is a
logic 1, a HIGH on the RXD input is considered a space.
