Intel® Serial IO Generic SPI (GSPI) Controllers

The PCH implements three generic SPI interfaces to support devices that uses serial protocol for transferring data.

Each interface consists of a clock (CLK), chip select (CS) and two data lines (MOSI and MISO).

The GSPI interfaces support the following features:

  • Support bit rates up to 20 Mbits/s
  • Support data size from 4 to 32 bits in length and FIFO depths of 64 entries
  • Support DMA with 128-byte FIFO per channel (up to 64-byte burst)
  • Full duplex synchronous serial interface
  • Support the Motorola’s* SPI protocol
  • Operate in master mode only
Note:Slave mode is not supported.
