Part Number: TCA9543A
In a configuration where you are using multiple master devices with each master device having an I2C connection to a single TCA9543APWR that is connected to a common shared I2C bus. If each TCA9543APWR had the same I2C address pin selection, could a master device reconfigure the switch connections of another TCA9543APWR, or can the switch "outputs" (SC0,SD0,SC1,SD1) only be configured through SCL/SDA on the "input" side? I want to make sure SoC 1 couldn't reconfigure the TCA9543 of SoC 2 if they share an address and therefore the messages would go to both devices.
Our primary concern is that once all SoCs come up and configure the switches, if all are configured on the same bus (SC0/SD0 for instance) would the I2C messages be messed up due to all switches sharing the same I2C address?
