DESCRIPTION
O UART channel 4 Request to Send or general purpose output (active low). See
description of RTS0# pin.
I UART channel 4 Clear to Send or general purpose input (active low). See
description of CTS0# pin.
O UART channel 4 Data Terminal Ready or general purpose output (active low).
See description of DTR0# pin.
I UART channel 4 Data Set Ready or general purpose input (active low). See
description of DSR0# pin.
I UART channel 4 Carrier Detect or general purpose input (active low).
I UART channel 4 Ring Indicator or general purpose input (active low).
O UART channel 5 Transmit Data or infrared transmit data.
I UART channel 5 Receive Data or infrared receive data. Normal RXD input
idles at logic 1 condition. The infrared pulses can be inverted internally prior
the decoder by FCTR[4].
