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.
