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. The infrared pulses typically idle LOW but can be inverted inter-
nally prior the decoder by FCTR[4].
