Address:
The SCI data register (SCDR) is the buffer between the internal data bus
and the receive and transmit shift registers. Reset has no effect on data
in the SCI data register.
R7/T7–R0/T0 — Receive/Transmit Data Bits
Do not use read/modify/write instructions on the SCI data register.
The baud rate register (SCBR) selects the baud rate for both the receiver
and the transmitter.

Reading address $0018 accesses the read-only received data bits,
R7:R0. Writing to address $0018 writes the data to be transmitted,
T7:T0. Reset has no effect on the SCI data register.
