WebNov 18, 2024 · Serial Peripheral Interface (SPI) is a synchronous serial data protocol used by microcontrollers for communicating with one or more peripheral devices quickly over short distances. This article was revised on 2024/11/18 by Karl Söderby. Controller/peripheral is formerly known as master/slave. Arduino no longer supports the use of this terminology. WebIf one writes D0 D1 D2 D3 bytes using 1-1-1 mode, and uses 8D-8D-8D SPI mode for reading, it will read back D1 D0 D3 D2. Swapping the bytes is a bad design decision because this may introduce some endianness problems. It can affect the boot sequence if the entire boot sequence is not handled in either 8D-8D-8D mode or 1-1-1 mode.
