public byte GpioDirectionMask { get; set; }

Gets or sets the state of the GPIO pins on the FT232 device.

public byte GpioState { get; set; }

Gets an array of all supported speeds of the SPI bus.

public Frequency[] SupportedSpeeds { get; }

Gets the current SPI clock configuration.

public SpiClockConfiguration Configuration { get; }

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

Writes data from the write buffer to a peripheral on the bus while reading return data into the read buffer.
