Technical Data
276
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.
Reset:
R7/T7:R0/T0 — Receive/Transmit Data Bits
The SCI baud rate register (SCBR) selects the baud rate for both the
receiver and the transmitter.
