| uint32_t spi_options_t::baudrate |
Preferred baudrate for the SPI.
Referenced by sd_mmc_spi_internal_init(), and spi_setupChipReg().
| uint8_t spi_options_t::bits |
Number of bits in each character (8 to 16).
Referenced by spi_setupChipReg().
| uint8_t spi_options_t::modfdis |
Disables the mode fault detection.
With this bit cleared, the SPI master mode will disable itself if another master tries to address it.

The SPI channel to set up.
