PCA9548A: Bus Recovery Sequence

Part Number: PCA9548A

Hi Team,

I have a question regarding the PCA9548A. How will the device react to the Bus recovery sequence:

1-Send 9 clock pulses on SCL line

2-Ask the master to keep SDA High until the “Slave-Transmitter” releases the SDA line to perform the ACK operation

3-Keeping SDA High during the ACK means that the “Master-Receiver” does not acknowledge the previous byte receive

4-The “Slave-Transmitter” then goes in an idle state

5-The master then sends a STOP command initializing completely the bus

 

If a port or several ports is open on the PCA9548A it will just pass this commands through right? If not what will happen?

Thanks for the help here.

Bets Regards,

Joe
