SPI0 control register.
FDUMMY_OUT | In the dummy phase the signal level of spi is output by the spi controller. |
FCMD_DUAL | Apply 2 signals during command phase 1:enable 0: disable |
FCMD_QUAD | Apply 4 signals during command phase 1:enable 0: disable |
FASTRD_MODE | This bit enable the bits: spi_mem_fread_qio, spi_mem_fread_dio, spi_mem_fread_qout and spi_mem_fread_dout. 1: enable 0: disable. |
FREAD_DUAL | In the read operations, read-data phase apply 2 signals. 1: enable 0: disable. |
Q_POL | The bit is used to set MISO line polarity, 1: high 0, low |
D_POL | The bit is used to set MOSI line polarity, 1: high 0, low |
FREAD_QUAD | In the read operations read-data phase apply 4 signals. 1: enable 0: disable. |
WP | Write protect signal output when SPI is idle. 1: output high, 0: output low. |
FREAD_DIO | In the read operations address phase and read-data phase apply 2 signals. 1: enable 0: disable. |
FREAD_QIO | In the read operations address phase and read-data phase apply 4 signals. 1: enable 0: disable. |
