TCA9548A: User Guide/I2C API

Steve Mr
Prodigy 10 points
Part Number: TCA9548A

Hello,

I'm looking for a user guide that describes the registers available in the TCA9548A to read/write.  I want to query a basic ID/manufacturer/part number as part of a larger probe process to ensure the I2C muxer is in tact BEFORE I attempt to select a channel and query a downstream device.

    Hi Steve,

    This device only has a single register called the "control register" in which the state of each channel (enabled or disabled) is represented by a single bit. You can read more about it in section 8.5.4 of the datasheet. Please let us know if anything is not clear.

    Regards,
    Max
