2.3.8 Operation with Multiple Master

The application should use repeated starts to address the MPR03X to avoid bus confusion between I²C masters.On a I²C bus,

once a master issues a start/repeated start condition, that master owns the bus until a stop condition occurs. If a master that does

not own the bus attempts to take control of that bus, then improper addressing may occur. An address may always be rewritten

to fix this problem. Follow I²C protocol for multiple master configurations.
