ORed with serial control register if P/S = "L" (Connected to ground) Audio data master/slave mode select pin "L": slave mode, "H": master mode (Connected to ground) Audio serial data clock pin Input/output channel clock pin DAC1 audio serial data input pin DAC2 audio serial data input pin DAC3 audio serial data input pin Audio serial data output pin AUX audio serial data input pin (Connected to ground) Double speed sampling mode pin "L": normal speed, "H": double speed ORed with serial control register if P/S = "L" (Connected to ground) De-emphasis pin ORed with serial control register if P/S = "L" (Connected to ground) Master clock output pin (Not used) Digital power supply pin Digital ground pin Power-down & reset pin When "L", the AK4526 is powered-down and the control registers are reset to default state. If the state of P/S, M/S, CAD0-1 changes, then the AK4526 must be reset by PD. X'tal oscillator select/test mode pin "H": X'tal oscillator selected "L": External clock source selected "NC": If pin is floating then test mode is enabled.
