(6) Clocked serial interface read-only reception buffer registers Low (SIRBEL0 to SIRBEL2)
The SIRBELn register is an 8-bit buffer register that stores receive data (n = 0 to 2).
These registers are read-only, in 8-bit units.
In addition to reset input, this register can also be initialized by clearing (0) the CSIE bit of the
CSIMn register.
The SIRBELn register is the same as the lower byte of the SIRBn register. It is used to read the
contents of the SIRBLn register.

Cautions: 1. The receive operation is not started even if data is read from the SIRBELn
register.
2. The SIRBELn register can be read only if the 8-bit data length has been set (CCL
bit of CSIMn register = 0).
