11.2
The SCI module has a total of two external pins.
11.2.1
The TXD pin transmits SCI (standard or infrared) data. It will idle high in either mode and is high
impedance anytime the transmitter is disabled.
11.2.2
The RXD pin receives SCI (standard or infrared) data. An idle line is detected as a line high. This input is
ignored when the receiver is disabled and should be terminated to a known voltage.
11.3
This section provides a detailed description of all the SCI registers.
