SPI TXDAT addressOffset = 0x01C

The TXDAT register is written in order to send data via the SPI transmitter when control information is not changing during the transfer (see SPI TXDATCTL addressOffset = 0x018). That data will be sent to the transmit shift register when it is available, and another character may then be written to TXDAT.
