(10) Clocked serial interface initial transmission buffer registers Low (SOTBFL0 to SOTBFL2)
The SOTBFLn register is an 8-bit buffer register that stores initial transmission data in the repeat
transfer mode (n = 0 to 2).
The transmission operation is not started even if data is written to the SOTBFLn register.
These registers can be read/written in 8-bit units.
The SOTBFLn register is the same as the lower bytes of the SOTBFn register.

Caution: Access the SOTBFLn register only when the 8-bit data length has been set (CCL bit
of CSIM0 register = 0), and only in the idle state (CSOT bit of CSIMn register = 0). If
the SOTBFLn register is accessed during data transfer, the data cannot be
guaranteed.
