C BUS is inter bus system controled by 2 lines (SDA, SCL).
Data are transmitted and received in the units of byte and Acknowledge.
It is transmitted by MSB first from the Start conditions.
[Control registers]
Control registers are data sent from the master for determining the switch conditions.
The data format is set as shown in the following figure.
Out of the Address byte, first 7bit are assigned to the slave address, while the residual 1bit is assigned to the
R/W bit.
Set the R/W bit to 0 when data are used control registers.
As MM1495 slave address, either 90H or 92H can be selected according to the ADR
terminal conditions. When ADR terminal is L, 90H is selected.
The following figure indicates the control contents of control registers and switches.
Each bit of control registers is reset to 0, when power-on.
MM1495 consists of one address byte and three control data bytes (4bytes in total).
All data over the limited length (5th and subsequent bytes) are fully neglected.
For details of the control contents of switches, refer to the separate table.
