DESCRIPTION
I UART channel 2 Receive Data or infrared receive data. Normal RXD input
idles at HIGH condition. The infrared pulses can be inverted prior to decoding
by setting FCTR bit [4].
O UART channel 2 Request to Send or general purpose output (active LOW).
I UART channel 2 Clear to Send or general purpose input (active LOW).
O UART channel 2 Data Terminal Ready or general purpose output (active
LOW).
I UART channel 2 Data Set Ready or general purpose input (active LOW).
I UART channel 2 Carrier Detect or general purpose input (active LOW).
I UART channel 2 Ring Indicator or general purpose input (active LOW).
O UART channel 3 Transmit Data or infrared transmit data.
