Troy,

Following Tom's suggestion, I am trying to use linker script to put the srdata
into SRAM. But I still have a concern regarding initializing the srdata. I don't
see it is initialized anywhere. Do you presume the data is wiped out before the
driver runs? If that's the case, I need to clear the data somewhere in my code.
