M / S should be set to "H" for SW1. SDTI, LRCK, BICK of PORT3 should be connected to SDTO, LRCK, BICK for DSP. In case of supplying MCKO from DSP, the test pin(MCKO)on sub board should be connected to MCLK of DSP. The system clock can be supplied by two ways below.
1) Supplied MCKI from J17
JP12 PHASE JP13 BICK JP16 MCLK JP17 EXT JP18 LRCK JP19 SDTI
ADC MCKO EXT DIR
2) Supplied MCKI from MCLK(PORT3)

When all interface signals are fed externally, JP14 (MKFS) and JP15 (BCFS) are not used. Therefore, JP14 (MKFS) should be set to "x1" and JP15 (BCFS) should be set to "64fs". JP12 (PHASE) is jumper which decides polarity of BICK, JP12 should be set to "THR" or "INV" according to audio interface format.
