									= “L” (Connected to ground)
						ORed with serial control register if P/S
					I	MCKO clock frequency select pin
2		MCLK
						“L”: MCLK, “H”: MCLK/2. ORed with serial control register if P/S					“L” (Connected to ground)
										=
						Audio data master/slave mode select pin
3			S/M		I
						“L”: slave mode, “H”: master mode (Connected to ground)
4		BCLK			I/O	Audio serial data clock pin
