21. Serial Communication Interface with FIFO (SCIF)
21.3.5
SCSMR is a 16-bit register used to set the SCIF's serial communication format and select the baud
rate generator clock source.
SCSMR can always be read from and written to by the CPU.

Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Communication Mode
Selects asynchronous mode or clocked synchronous
mode as the SCIF operating mode.
0: Asynchronous mode
1: Clocked synchronous mode
Character Length
Selects 7 or 8 bits as the asynchronous mode data
length. In clocked synchronous mode, the data length is
fixed at 8 bits regardless of the CHR bit setting. When
7-bit data is selected, the MSB (bit 7) of SCFTDR is not
transmitted.
0: 8-bit data
