   ## Summary
   In some state values the transfer is restarted in irq handler and the 
interrupts are disabled in the end of the function after the transfer is 
started. This may cause early interrupts to be accidentally cleared before they 
are handled leading timeout error. Interrupt clearing should be done before the 
transfer is restarted.
   
   ## Impact
   If interrupts are cleared before the transfer restart the slow bus/memory 
access does not affect to the timing of the start/clear operations and 
interrupts are not accidentally cleared.
   
   ## Testing
   Running heavy load in other operating system in dual OS setup to see there 
is no issues in i2c transfers.
