(1) Loopback mode
MCLK, BICK and LRCK are fed from AK4586. JP26(SDTI1), JP27(SDTI2) and JP28(SDTI3) should be
shorted.
JP26(SDTI1) shorted → Loopback outputs to ROUT1, LOUT1
JP27(SDTI2) shorted → Loopback outputs to ROUT2, LOUT2
JP28(SDTI3) shorted → Loopback outputs to ROUT3, LOUT3
Nothing should be connected to PORT4(AC3). Clock operation mode of the AK4586 should be set to X’tal
mode by the control software packed with the AKD4586. Clock operation mode is set by CM1-0 bit of
Addr=02H.
