[control registers] control registers are data sent from the master for determining the switch condition of the mm1422 series. a a p a s address byte control data slave address r / w 10010000 control register 1 b7 b6 b5 b4 b3 b2 b1 b0 control register 2 b7 b6 b5 b4 b3 b2 b1 b0
mitsumi canal+compatible i 2 c bus controlled 4-input 3-output av switch mm1422, 1423, 1442, 1443 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. 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. b7 b6 b5 b4 b3 b2 b1 b0 out 1 select out 2 select out 3 select fs ctrl b7 b6 b5 b4 b3 b2 b1 b0 0, 12db select port 1 ctrl port 2 ctrl audio out2 gain select audio out3 gain select mute [control register 1] [control register 2] s slave address r/w a status register na p 10010001 b7b6b5b4b3b2b1b0 address byte status data
