Serial Communications Interface Module (SCI)
11.7.2 RxD (Receive Data)
When the SCI is enabled (ENSCI=1), the PTB3/RxD pin becomes the serial data input, RxD, to the SCI
receiver regardless of the state of the DDRB3 bit in data direction register B (DDRB).
11.8 I/O Registers
These I/O registers control and monitor SCI operation:

SCI control register 1 (SCC1)
SCI control register 2 (SCC2)
SCI control register 3 (SCC3)
SCI status register 1 (SCS1)

SCI data register (SCDR)
SCI baud rate register (SCBR)
The PTB2/TxD pin is an open-drain pin when configured as an output.
Therefore, when configured as a general purpose output pin (PTB2), a
pullup resistor must be connected to this pin.
