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