Peripheral SPI[edit | edit source]
The Enhanced Configurable Serial Peripheral Interface (ECSPI) is a full-duplex, synchronous, four-wire serial communication block.
Description[edit | edit source]
Three SPI interface are available on ORCA based on iMX8MPlus SoC.
The SPI port supports the following standards and features:
- Full-duplex synchronous serial interface
- Master/Slave configurable
- One Chip Select (SS) signal
- Transfer continuation function allows unlimited length data transfers
- 32-bit wide by 64-entry FIFO for both transmit and receive data
- Polarity and phase of the Chip Select (SS) and SPI Clock (SCLK) are configurable
- Direct Memory Access (DMA) support
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
