Host clears DONE bit to signal IPC target it has completed the operation. Once this is done, IPC target i.e. DSP may proceed with the next reply, filling registers with new portion of data. Because of this, host should always read all registers prior to clearing DONE and BUSY bits to ensure no desynchronization happens the time in between clearing bits and reading message data (here, extension).
