16.3.4
SCFTDR is an 8-bit 64-stage FIFO data register that stores data for serial transmission.
If SCTSR is empty when transmit data is written to SCFTDR, the SCIF transfers the transmit data
written in SCFTDR to SCTSR and starts serial transmission.
SCFTDR is a write-only register, and cannot be read by the CPU.
The next data cannot be written when SCFTDR is filled with 64 bytes of transmit data. Data
written in this case is ignored.
16.3.5
SCSMR is a 16-bit readable/writable register used to set the SCIF’s serial transfer format and
select the baud rate generator clock source and the sampling rate.
