Does STM32 HAL support sending “commands�? over I2C to FRAM IC like MB85RC64TA?

Such “commands�? specified by this FRAM IC vendor are supposed to set “Speed Modes�?, set a “Sleep Mode�?, etc. 

This require sending multiple START conditions followed by some data.

The HAL I2C driver does support repeated start. (No idea what is multiple start)

What the I2C peripheral can do is likely STM32 family related.

I don't know there's specific accommodation for out-of-ordinary use cases, but I'm pretty sure any signalling could be emulated with the application of effort.
