(6) Clocked serial interface read-only reception buffer registers L0, L1 (SIRBEL0, SIRBEL1)
The SIRBELn register is an 8-bit buffer register that stores receive data (n = 0, 1).
These registers are read-only in 8-bit or 1-bit units.
In addition to reset input, this register can also be initialized by clearing (0) the CSICAEn bit of the CSIMn
register.
The SIRBELn register is the same as the SIRBLn 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).
