Receive data buffer register 3n (SIRB3n, SIRB3nL, SIRB3nH)
The SIRB3n register is a 16-bit buffer register that stores receive data. It is overlayed by an 8-bit
buffer register SIRB3nL on the lower 8 bits, and an 8-bit buffer register SIRB3nH on the higher 8
bits.
By consecutively reading this register in the consecutive mode (TRMDn bit of the CSIM3n
register = 1), the received data in the CSIBUFn register can be sequentially read while the
CSIBUFn pointer for reading is incremented.
In the single mode (TRMDn bit of the CSIM3n register = 0), received data is read by reading the
SIRB3n register and it is judged that the SIRB3n register has become empty.
The SIRB3n register is read-only, in 16-bit units.
The SIRB3nL and SIRB3nH registers are read-only, in 8-bit units.
Reset input clears the SIRB3n register to 0000H, and the SIRB3nL and SIRB3nH registers to 00H
accordingly.
In addition to reset input, the SIRB3n as well as the SIRB3nL and SIRB3nH registers are initialized
by clearing (to 0) the CSICAEn bit of the CSIM3n register.
