What is the SPI 2-bit transfer mode and how to use it?
Posted: 27 Mar 2017, 14:01
The 2-bit transfer mode means that the SPI controller transmits 2-bit data output at the same edge of serial clock, and meanwhile it also receives 2-bit data input at the opposite edge of serial clock during a serial clock cycle. Accordingly, one SPI Master controller can access data with two external Slave devices simultaneously.
