multiple port selection for CY8C9560A

In my project, I need to have multiple ports of IO expander CY8C9560A simultaneously configured as output .

I would like to know whether the status of a port will remain valid if a different port is selected using repeat start feature of I2C?

I am a bit confident that the value will be retained but let me check it once before confirming.

 

Best regards,

Pushek

It would be great if I could have multiple ports selected simultaneoulsy. Did you get a positive result in checking?

Thanks for your effort.
