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.
UART channel 0 Carrier Detect or general purpose input (active low).
UART channel 0 Ring Indicator or general purpose input (active low).
UART channel 1 Transmit Data or infrared transmit data.
UART channel 1 Receive Data or infrared receive data. Normal RXD input
idles at logic 1 condition. The infrared pulses can be inverted internally prior
to the decoder by FCTR[4].
UART channel 1 Request to Send or general purpose output (active low).
See description of RTS0# pin.
UART channel 1 Clear to Send or general purpose input (active low). See
description of CTS0# pin.
UART channel 1 Data Terminal Ready or general purpose output (active low).
See description of DTS0# pin.
UART channel 1 Data Set Ready or general purpose input (active low). See
description of DSR0# pin.
UART channel 1
UART channel 1 Ring Indicator or general purpose input (active low).
UART channel 2 Transmit Data or infrared transmit data.
UART channel 2 Receive Data or infrared receive data. Normal RXD input
idles at logic 1 condition. The infrared pulses can be inverted internally prior
to the decoder by FCTR[4].
UART channel 2 Request to Send or general purpose output (active low).
See description of RTS0# pin.
UART channel 2 Clear to Send or general purpose input (active low). See
description of CTS0# pin.
UART channel 2 Data Terminal Ready or general purpose output (active low).
See description of DTS0# pin.
UART channel 2 Data Set Ready or general purpose input (active low). See
description of DSR0# pin.
UART channel 2
UART channel 2 Ring Indicator or general purpose intput (active low).
UART channel 3 Transmit Data or infrared transmit data.
UART channel 3 Receive Data or infrared receive data. Normal RXD input
idles at logic 1 condition. The infrared pulses can be inverted internally prior
to the decoder by FCTR[4].
UART channel 3 Request to Send or general purpose output (active low).
See description of RTS0# pin.
UART channel 3 Clear to Send or general purpose input (active low).d. See
description of CTS0# pin.
