lines will be disabled.
Examples:
. Enable chip-select line 3: `NEORV32_SPI->DATA = (1 << SPI_DATA_CMD) | (1 << 3) | 3;`
. Enable chip-select line 7: `NEORV32_SPI->DATA = (1 << SPI_DATA_CMD) | (1 << 3) | 7;`
. Disable all chip-select lines: `NEORV32_SPI->DATA = (1 << SPI_DATA_CMD) | (0 << 3);`
. Send data byte `0xAB`: `NEORV32_SPI->DATA = (0 << SPI_DATA_CMD) | 0xAB;`
* Enable chip-select line 3: `NEORV32_SPI->DATA = (1 << SPI_DATA_CMD) | (1 << 3) | 3;`
* Enable chip-select line 7: `NEORV32_SPI->DATA = (1 << SPI_DATA_CMD) | (1 << 3) | 7;`
* Disable all chip-select lines: `NEORV32_SPI->DATA = (1 << SPI_DATA_CMD) | (0 << 3);`
* Send data byte `0xAB`: `NEORV32_SPI->DATA = (0 << SPI_DATA_CMD) | 0xAB;`
Since all SPI operations are controlled via the FIFO, entire SPI sequences (chip-enable, data transmissions, chip-disable)
can be "programmed". Thus, SPI operations can be executed without any CPU interaction at all.
