  Log Message:
  -----------
  Maior Improvement: We have itentified that a mainloop reading the BUSY bit 
can clear an ADDR interupt. Moreover we have identified that when writing a 
Start ClearStop to CR1 in a single machine code does not clear the pending Stop 
but adds a start not ever folowed by an extra STOP. clearing stop then writing 
start canceled the needed stop, and setting start and then clearing stop still 
sometimes added a second unwanted stop after the start the followed the wanted 
stop. This means the 2 reasons for stopping interrupts are suddenly gone...
