(5) Clocked serial interface read-only receive buffer registers 0, 1 (SIRBE0, SIRBE1)
The SIRBEn register is a 16-bit buffer register that stores receive data (n = 0, 1).
These registers are read-only, in 16-bit units.
In addition to reset input, this register can also be initialized by clearing (0) the CSICAEn bit of the CSIMn
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 (CCL bit of CSIMn
register = 1).
