Configuration structure of the SPI master driver instance.
| uint8_t nrfx_spi_config_t::miso_pin |
MISO pin number (optional).
Set to NRFX_SPI_PIN_NOT_USED if this signal is not needed.
| uint8_t nrfx_spi_config_t::mosi_pin |
MOSI pin number (optional).
Set to NRFX_SPI_PIN_NOT_USED if this signal is not needed.
| uint8_t nrfx_spi_config_t::orc |
Overrun character.
This character is used when all bytes from the TX buffer are sent, but the transfer continues due to RX.
| uint8_t nrfx_spi_config_t::ss_pin |
Slave Select pin number (optional).
Set to NRFX_SPI_PIN_NOT_USED if this signal is not needed. The driver supports only active low for this signal. If the signal must be active high, it must be controlled externally.
