(1) CSIFn receive data register (CFnRX)
(2) CSIFn transmit data register (CFnTX)
The CFnRX register is a 16-bit buffer register that holds receive data.
This register is read-only, in 16-bit units.
The receive operation is started by reading the CFnRX register in the reception enabled status.
If the transfer data length is 8 bits, the lower 8 bits of this register are read-only in 8-bit units as the CFnRXL
register.
Reset sets this register to 0000H.
In addition to reset input, the CFnRX register can be initialized by clearing (to 0) the CFnPWR bit of the
CFnCTL0 register.
The CFnTX register is a 16-bit buffer register used to write the CSIFn transfer data.
This register can be read or written in 16-bit units.
The transmit operation is started by writing data to the CFnTX register in the transmission enabled status.
If the transfer data length is 8 bits, the lower 8 bits of this register are read-only in 8-bit units as the CFnTXL
register.
Reset sets this register to 0000H.
