CSIB transmit data register (CBnTX)
The CBnTX register is a 16-bit buffer register used to write the CSIB transfer data. It is overlayed
by an 8-bit register CBnTXL on the lower 8 bits, which is used when the transfer data length is
8 bits.
The transmit operation is started by writing data to the CBnTX or CBnTXL registers during
transmission enabled status.
The CBnTX register can be read or written in 16-bit units.
The CBnTXL register can be read or written in 8-bit units.
Reset input clears the CBnTX register to 0000H, and the CBnRXL register to 00H accordingly.
In addition to reset input, the CBnTX and CBnTXL registers can be initialized by clearing (to 0) the
CBnPWR bit of the CBnCTL0 register.
