   Don't forget that I2C have a flexible transfer rate based on bit
   handshake, so the protocol is easier to implement by software as strict
   transfer rate need not be adhere to.

   Theoretically you can run down to 0 Hz, i.e. suspended in the middle
   of a transfer (while your uC is processing another interrupt, for example),
   without any problem.
