10 / 15 page LC75106V No. A2153-10/15 Control Data Structure (Serial Data Input) The setting of LC75106 can be controlled with I 2C Bus. All the settings can be controlled by I 2C Bus at the stereo signal internal connection modes (CS terminal = “H”), and all the volumes except the stereo source control can be set at the stereo signal outside connection modes (CS terminal = “L”). The karaoke system can be made from external resistance by doing I 2C Bus Line in Pull Up at the stereo signal outside connection modes. 1) The explanation of I 2C Bus I 2C Bus (Inter IC Bus) is the bus system which the PHILIPS company developed. It does controls such as the start, the stop by two control signals of SDA (Serial Data) and SCL (Serial Clock). The output of each signal is open drain and forms out of wired OR. S; Start condition/P; Stop condition/ACK; Acknowledge Data is transmitted in the MSB first. 1 unit is composed of 8 bits and ACK is put back from the slave to confirm. Slave IC reads data with rising edge of SCL. Master IC changes data by falling edge in SCL. 2) The control register Table1 Slave Address MSB LSB 0 0 1 1 1 0 0 0 Note; LC75106 is reception exclusive use. It depends and it uses LSB by the “0” fixation. • I2C data Function Sub Address Data BINARY HEX D7 D6 D5 D4 D3 D2 D1 D0 Stereo line select/Mic1 volume 0000 0001 01 LD2 LD1 LD0 KEY M1D3 M1D2 M1D1 M1D0 Mic2 volume/Test 0000 0010 02 M2D3 M2D2 M2D1 M2D0 TEST3 TEST2 TEST1 TEST0 Delay time/ECHO volume 0000 0011 03 0 DT2 DT1 DT0 0 ED2 ED1 ED0 Feed back volume 0000 0100 04 0 FB2 FB1 FB0 0 0 0 0 SDA SCL S ACK ACK P |
