20.4.3. Transfer Modes

When transferring data on the serial bus, the SPI controller operates one of several modes. The transfer mode (TMOD) is set by writing to the TMOD field in control register 0 (CTRLR0).

Note: The transfer mode setting does not affect the duplex of the serial transfer. TMOD is ignored for Microwire transfers, which are controlled by the MWCR register.  †
