CONFIG_SPI_DW_FIFO_DEPTH¶

RX and TX FIFO Depth

Type: int

Help¶

Corresponds to the SSI_TX_FIFO_DEPTH and
SSI_RX_FIFO_DEPTH of the DesignWare Synchronous
Serial Interface. Depth ranges from 2-256.

Direct dependencies¶

(SPI_DW && SPI && BOARD_EM_STARTERKIT) || (SPI_DW && SPI && BOARD_HSDK) || SOC_INTEL_S1000 || SOC_INTEL_S1000 || (SPI_DW && SPI)

(Includes any dependencies from ifs and menus.)
