    SPI clock generation in master mode is directly connected to sending data. SPI is bi-directional. If you don't want to send anything, you may simply disable the UART I/O by not setting the PxSEL bit for the MOSI pin.
    You'll still need to stuff the TXBUF register in order to make the USCI generate clock pulses. And for every byte you send (into the void) you'll get (one byte later) one byte received.
