78M6610+LMU Data Sheet  
I2C Interface  
The 78M6610+LMU has an I2C interface available at the SDAI, SDAO, and SCL pins. The interface  
supports I2C slave mode with a 7-bit address and operates at a data rate up to 400kHz. The figure below  
shows two possible configurations. Configuration A is the standard configuration. The double pin for SDA  
also allows for isolated configuration B.

Device Address Configuration  
By default, there are only four possible addresses for the MAX78615+LMU as defined by two external  
address pins. To expand the potential address of the device to the entire 7-bit address range for I2C, one  
can set I2C address bits 6 through 2 in the DEVADDR register and save them to Flash memory as the  
default.  
A change in the device address takes effect following a power-on or reset. During the initialization, the  
DEVADDR register value is restored from Flash memory and the state of the address pins are acquired.  
DEVADDR bits 23 through 5 are not used and have no effect on the device address.
