==Peripheral SPI ==
The Enhanced Configurable Serial Peripheral Interface (ECSPI) is a full-duplex, synchronous, four-wire serial communication block.
=== Description ===
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===
The Pin mapping is described in the [[ORCA SOM/ORCA Hardware/Pinout_Table | Pinout table section]]
