+#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).
