USAGE of DEMO Board 1. DSP always operates in slave mode. 2. In either analog or digital input, the signal is inputted to SDI0 port. 3. In case of both digital and analog output, DSP input port is only digital input. When analog signal is used, disconnect

digital input signal from this demo board.

Jumper setting description 1. Set up the 5V power supply line. NOR (*default) : AC Adapter USB : 5V of USB port 2. Set up the jumper to input the sound signal to input ports SDI0 (*) :J4 set SDI1 :J5 set SDI2 : J7 set SDI3 : J8 set 3. Set up the jumpers to output to SEL_AOUT and SEL_DOUT connecter. SDO0 : J15 SDO0 set SDO1 : J15 SDO1 set SDO2 : J17 SDO2 set SDO3 (*) :J17 SDO3 set
