|Registers / SPI0/1 Register description|
The TXCTL register provides a way to separately access control information for the SPI. These bits are another view of the same-named bits in the TXDATCTL register (see SPI TXDATCTL addressOffset = 0x018). Changing bits in TXCTL has no effect unless data is later written to the TXDAT register. Data written to TXDATCTL overwrites the TXCTL register.
When control information needs to be changed during transmission, the TXDATCTL register should be used (see SPI TXDATCTL addressOffset = 0x018) instead of TXDAT. Control information can then be written along with data.
