HINBSY, GPIO8 — Input Host Message Status, General Purpose I/O

This pin indicates that serial or parallel communication data written to the DSP has not been

read yet. This pin can act as a general-purpose input or output that can be individually

configured and controlled by DSPC. This pin has an internal pull-up. BIDIRECTIONAL -
