It transmits and receives data through 2 (SDA, SCL) lines. Data are transmitted and received in the units of bytes by MSB first from the start condition. [Control registers] Control registers are data sent from the master for determining the switch condition of the MM1422 series. S Slave address 1 0 0 1 0 0 Address byte R/W 0 0 A Control Register 1 b7 b6 b5 b4 b3 b2 b1 b0 A Control Register 2 b7 b6 b5 b4 b3 b2 b1 b0 Control data A P AV Switch for I2C BUS Control, 4-input, 3-output and Canal Plus Compatible MM1422, 1423, 1442, 1443 MITSUMI The data format of the MM1422 series is set as shown in the above figure. Out of the address bytes, first 7 bits are assigned to the slave addresses, while the residual 1 bit is assigned to the R/W bit. Set the R/W bit to 0 when data are used as control registers. Slave address of the MM1422 series is 90H. Each bit of control registers is reset to 0. MM1422 series consists of one address byte and two control data bytes(3 bytes in total). For details of the control contents of control register 1 and 2, refer to the separate table. [Control Register 1] b7 b6 b5 OUT 1 select b4 b3 OUT 2 select b2 b1 OUT 3 select b0 FS CTRL [Control Register 2] b7 b6 b5 b4 0, 12dB select Port 1 CTRL Port 2 CTRL b3 b2 Audio OUT2 gain select b1 b0 Audio OUT3 gain select Mute All data over the limited length (4th and subsequent bytes) are fully neglected. Because of this, the faulty operation that switch changes by the data after the 4th byte doesn't occur. Each audio output can be set to mute by setting MUTE terminal to high. [Status registers] There is no preparation of the status register in MM1422 series. A status register returns all the 1 when is set in the R/W bit.
