   4 #no sense to use TRST, but use TMS instead.
   5 #
   6 #The annoying thing with tying SRST & TRST together is that
   7 #there is no way to halt the CPU *before and during* the
   8 #SRST reset, which means that the CPU will run a number
   9 #of cycles before it can be halted(as much as milliseconds).
