 Name:         »dsptristate« - Coordinate external DSP hardware

 Opcode:       137

 Syntax:       int32_t dsptristate( int16_t dspxmit, int16_t dsprec );

 Description:  The XBIOS routine dsptristate uncouples connections 
               from the multiplexer connection matrix when external 
               hardware is connected to the SSI port of the DSP.

                Parameter  Meaning

                dspxmit    The value 0 disconnects the multiplexer 
                           from the corresponding connection, while 1 
                           permits the connection.

                dsprec     The value 0 disconnects the multiplexer 
                           from the corresponding connection, while 1 
                           permits the connection.

 Return value: The function returns the value 0 if the operation was 
               successfull, or non-zero otherwise.

               Falcon series.
