10 / 13 page LA72715NV Fig.1 DATA STRUCTURE “WRITE” mode START Condition Slave Address R/W L ACK Control data ACK STOP condition Fig.2 DATA STRUCTURE “READ” mode START condition Slave Address R/W H ACK Internal Data * ACK STOP condition ∗ The output data synchronizes with the clock of SCL pin. Then the ACK output is made after the output data. bit8 is result of STERO DET (H : STEREO) bit7 is result of BILINGUAL DET (H : BILINGUAL) bit6 is Initial Condition ‘H’ bit5 to bit1 are fixed to ‘L’ (3) Initialize This IC is initialized for circuit protection. Initial condition is “01h (Main-mode) ”.
