(5) Clocked serial interface read-only reception buffer register n (SIRBEn)
The SIRBEn register is a 16-bit buffer register that stores receive data.
These registers are read-only, in 16-bit units.
In addition to reset input, this register can also be initialized by clearing (0) the CSI0En bit of the CSIM0n
register.
The SIRBEn register is the same as the SIRBn register. It is used to read the contents of the SIRBn register.
Cautions 1. The receive operation is not started even if data is read from the SIRBEn register.
2. The SIRBEn register can be read only if the 16-bit data length is set (CCLn bit of CSIM0n
register = 1).

(6) Clocked serial interface read-only reception buffer register nL (SIRBEnL)
The SIRBEnL register is an 8-bit buffer register that stores receive data.
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 CSI0En bit of the CSIM0n
register.
The SIRBEnL register is the same as the SIRBnL register. It is used to read the contents of the SIRBnL
register.
Cautions 1. The receive operation is not started even if data is read from the SIRBEnL register.
2. The SIRBEnL register can be read only if the 8-bit data length has been set (CCLn bit of
CSIM0n register = 0).
