The behavior for Byte Swap operation is not guaranteed for data frames other than 8-bit, 16-bit and 32bit. ... 4-wire SPI devices have four signals: 1. Clock (SPI CLK, SCLK) 2. Chip select (CS) 3. main out, subnode in (MOSI) 4. main in, subnode out (MISO) The device that generates the clock signal is called the main. Data transmitted between the main and the subnode is synchronized to the clock generated by the main. … See more To begin SPI communication, the main must send the clock signal and select the subnode by enabling the CS signal. Usually chip select is an active low signal; hence, the main must send a logic 0 on this signal to select the subnode. … See more In SPI, the main can select the clock polarity and clock phase.
