Section 15 Serial Communication Interface (SCI)
15.3.4
SCTDR is an 8-bit register that stores data for serial transmission. When the SCI detects that the
transmit shift register (SCTSR) is empty, it moves transmit data written in the SCTDR into
SCTSR and starts serial transmission. If the next transmit data has been written to SCTDR during
serial transmission from SCTSR, the SCI can transmit data continuously. SCTDR can always be
written or read to by the CPU.
15.3.5
SCSMR is an 8-bit register that specifies the SCI serial communication format and selects the
clock source for the baud rate generator.
The CPU can always read and write to SCSMR.

Description
Communication Mode
Selects whether the SCI operates in asynchronous or
clock synchronous mode.
0: Asynchronous mode
1: Clock synchronous mode
Character Length
Selects 7-bit or 8-bit data in asynchronous mode. In the
clock synchronous mode, the data length is always
eight bits, regardless of the CHR setting. When 7-bit
data is selected, the MSB (bit 7) of the transmit data
register is not transmitted.
0: 8-bit data
1: 7-bit data
