HIGH PERFORMANCE 2.25V TO 3.6V QUAD UART WITH FRACTIONAL BAUD RATE
REV. 1.0.1
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.
RX1
41
I
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.
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 descrip-
tion 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.
RX2
33
I
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.
RTS2#
38
O
UART channel 2 Request to Send or general purpose output (active low). See
description of RTS0# pin.
CTS2#
34
I
UART channel 2 Clear to Send or general purpose input (active low). See descrip-
tion of CTS0# pin.
DTR2#
39
O
UART channel 2 Data Terminal Ready or general purpose output (active low). See
description of DTS0# pin.
DSR2#
35
I
UART channel 2 Data Set Ready or general purpose input (active low). See
description of DSR0# pin.
CD2#
36
I
UART channel 2 Carrier Detect or general purpose input (active low).
RI2#
37
I
UART channel 2 Ring Indicator or general purpose intput (active low).
