#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).
