DSP. The JP8(LRCK2) and JP9(BICK2)’s right side should be connected to LRCK and BICK of DSP.
In case of supplying MCKO to DSP, the test pin(MCKO) should be connected to MCLK of DSP.

PORT2 (DSP) is used. MCLK,BICK,LRCK and SDATA are supplied from PORT2. The test pin(MCKO)
should be connected to MCLK of DSP. Nothing should be connected to PORT1 (DIR).
MCKO is needed for a synchronous singal of BICK and LRCK.
