Section 16 Serial Communication Interface with FIFO (SCIF)
16.3.4
SCFTDR is a 16-stage 8-bit FIFO register that stores data for serial transmission. When the SCIF
detects that the transmit shift register (SCTSR) is empty, it moves transmit data written in the
SCFTDR into SCTSR and starts serial transmission. Continuous serial transmission is performed
until there is no transmit data left in SCFTDR. SCFTDR can always be written to by the CPU.
When SCFTDR is full of transmit data (16 bytes), no more data can be written. If writing of new
data is attempted, the data is ignored.
16.3.5
SCSMR is a 16-bit register that specifies the SCIF serial communication format and selects the
clock source for the baud rate generator.
The CPU can always read and write to SCSMR.
