Before beginning configuration, trigger device cleaning by toggling the
transition also returns the device to the configuration state.

The configuration files for Intel Agilex devices can be highly compressed. During configuration, the decompression of the bit
stream inside the device requires the host to pause before sending more data. The Intel Agilex device asserts the
signal when the device is ready to accept data. The
