TCA9548A: TCA9548A Multiple Master

Ye Xiong

Part Number: TCA9548A

Once I’ve configured the TCA9548A device through SCL and SDA to have SC/SD0 and SC/SD1 connected/enabled. Is it possible for a Master on the secondary Bus SC/SD0 to access a slave device on the SC/SD1 channel or any channel if enabled/connected to the main?

All enabled channels are directly connected together. And I²C is a bidirectional protocol; on the electrical level, there is no difference between masters and slaves. So this is possible.
