Address $0076
Address $0077
The SCDR is a parallel register that performs two functions. Received
data in the RDR is read from this address when the SCI is receiving, and
data to be transmitted is written to this address when the SCI is
transmitting.
R8 and T8 — Receiver Bit 8 and Transmitter Bit 8
R/T[7:0] — Receiver/Transmitter Bits [7:0]
