Clocked serial interface initial transmission buffer registers (SOTBF0 to SOTBF2)
The SOTBFn register is a 16-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 SOTBFn register.
These registers can be read/written in 16-bit units.

Caution:
Access the SOTBFn register only when the 16-bit data length has been set (CCL bit
of CSIMn register = 1), and only in the idle state (CSOT bit of CSIMn register = 0). If
the SOTBFn register is accessed during data transfer, the data cannot be guaranteed.
