15.2.4
SCTDR1 is an 8-bit register that stores data for serial transmission.
When the SCI detects that SCTSR1 is empty, it transfers the transmit data written in SCTDR1 to
SCTSR1 and starts serial transmission. Continuous serial transmission can be carried out by
writing the next transmit data to SCTDR1 during serial transmission of the data in SCTSR1.
SCTDR1 can be read or written to by the CPU at all times.
SCTDR1 is initialized to H'FF by a power-on reset or manual reset, in standby mode, and in the
module standby state.
15.2.5
SCSMR1 is an 8-bit register used to set the SCI's serial transfer format and select the baud rate
generator clock source.
SCSMR1 can be read or written to by the CPU at all times.
SCSMR1 is initialized to H'00 by a power-on reset or manual reset, in standby mode, and in the
module standby state.
Bit 7—Communication Mode (C/A): Selects asynchronous mode or synchronous mode as the
SCI operating mode.
