System Reset
The AK4556 should be reset once by bringing the PDN pin “L” after power-up. In slave mode, reset and power down
states are released by MCLK and the internal timing starts clocking on the rising edge of LRCK in Mode LJ and Mode
2
LJ/RJ. In Mode I
S, it starts clocking on the falling edge of BCLK after the first rising edge of BCLK after the falling edge
of LRCK. The AK4556 is in power down state until LRCK is input. In master mode, reset and power down states are
released by MCLK. The internal timing also starts by MCLK.
