:Thanks for the reminder! It's one more reason to replace the
:current version of ColdReboot() - just imagine an interrupt
:coming along after the CPU-RESET has caused all interrupt
:vectors to disappear ...
But interrupts can't come along after the CPU executes a RESET instruction.
The RESET instruction clears all the interupt-enable bits. The existing
version of ColdReboot() is OK in that respect.
