I2C (Inter-Integrated Circuit)

The MS85RC1MTY has the two-wire serial interface; the I2C bus, and operates as a slave device.

The I2C bus defines communication roles of “master” and “slave” devices, with the master side holding the

authority to initiate control. Furthermore, the I2C bus connection is possible where a single master device is

connected to multiple slave devices in a party-line configuration. In this case, it is necessary to assign a

unique device address to the slave device, the master side starts communication after specifying the slave

to communicate by addresses.
