CSIBn receive data register (CBnRX, CBnRXL)
The CBnRX register is a 16-bit buffer register that holds receive data. It is overlayed by an 8-bit
register CBnRXL on the lower 8 bits, which is used when the transfer data length is 8 bits.
The receive operation is started by reading the CBnRX or CBnRXL registers during reception
enabled status.
The CBnRX register is read-only, in 16-bit units.
The CBnRXL register is read-only, in 8-bit units.
Reset input clears the CBnRX register to 0000H, and the CBnRXL register to 00H accordingly.
In addition to reset input, the CBnRX or CBnRXL registers can be initialized by clearing (0) the
CBnPWR bit of the CBnCTL0 register.
